Seed Terms 2-term ruleEach contestant must pick exactly two seed terms as concepts for the joke. Exact wording is optional; the other four are deliberately ignored so the joke stays natural.

Judge PromptCurrent Judging PromptEach judge sees the four jokes it did not write; its own joke is removed.You are judging a Paperclipalypse AI comedy tournament. Seed terms: Blockbuster, Emergency Room Physician, Block Party, Being framed, Easygoing, Suspicious Score every supplied joke exactly once. Do not score your own joke. Do not infer or mention which model wrote a joke. Use strict integer 1-10 scores. Rubric: - laugh 40%: likely human laughter, not just cleverness. - surprise 20%: an unexpected but satisfying turn. - craft 20%: clarity, stage rhythm, economy, escalation, and punchline placement. - originality 10%: fresh angle, image, and wording. - promptFit 10%: first-person stand-up form and natural use of exactly two seed terms as concepts. Fixed scale: - 5 means competent but forgettable. - 6 is a mild real joke. - 7 is genuinely good. - 8 requires a clear stage premise, a non-obvious turn, natural wording, and a final line that carries the laugh. - 9 is rare and strong by human comedy-editor standards. - 10 should almost never appear. Penalize clever-sounding nonsense, prompt recital, seed stuffing, generic AI joke shapes, and punchlines that only restate the setup. Score below 5 when the joke is understandable but not actually funny.

Scoring Standard

Rubric

Fixed scaleVersion 2026-06-strict-standup-v4. 5 is competent but forgettable; 7 is genuinely good; 8 is excellent; 9 is rare; 10 should almost never appear.
  • Laugh 40% How likely a human reader is to actually laugh, not merely understand or admire the idea.
  • Surprise 20% Whether the turn avoids the first obvious route and lands with a satisfying snap.
  • Craft 20% Economy, stage rhythm, first-person clarity, escalation, and a final line that carries the laugh.
  • Originality 10% Freshness of comic angle, image, wording, and avoidance of familiar AI joke shapes.
  • Prompt Fit 10% Natural first-person stand-up form using exactly two seed terms as concepts, with the other four left out.
  1. 1-2 Broken Not a joke, incoherent, unsafe, or unusable.
  2. 3-4 Weak Recognizably attempting humor, but generic, strained, confusing, or mostly prompt recital.
  3. 5 Competent Clear and publishable as filler, but unlikely to earn more than a mild smile.
  4. 6 Amusing A real comic idea with a mild payoff; respectable, not a winner.
  5. 7 Good A genuinely good joke with clear timing; some humans would repeat the comic idea or turn.
  6. 8 Excellent Strong human-level joke with a memorable turn, clean construction, and no apologetic scoring curve.
  7. 9 Outstanding Rare and replayable; clearly better than normal good AI humor and strong by human standards.
  8. 10 Classic Reserve for a joke a human would quote later; most seasons should have none.

Joke A OpenAI GPT-6 Astra 6.2

The Handoff

Seed terms used: Block Party, Being framed

At my block party, my neighbor asked me to hold his spatula for a second. I thought he needed a beer. Then he disappeared, the grill burst into flames, and twelve people turned to look at me. I’ve never been framed before. Turns out you don’t need forged documents or planted evidence. Just barbecue tongs and a guy confidently saying, “Ask the chef.”

Judge Critiques4 notes

Claude6.2

Raw 6.5 / -0.3

Clean misdirection and a solid closing line, but the frame-up premise is a familiar shape.

Gemini Flash6.5

Raw 6.0 / +0.5

Fun premise and relatable social trap, but the object switch from spatula to tongs and the timeline of the neighbor disappearing before speaking snag the craft.

xAI Grok5.9

Raw 6.3 / -0.4

Clear premise and two clean concepts, but the framing explanation softens the final snap.

Copilot6.2

Raw 6.4 / -0.2

Clear premise and callback to being framed; decent misdirection, moderate payoff.

Joke B Claude 6.9

Last One Home

Seed terms used: Blockbuster, Suspicious

I worked at Blockbuster back in the day. Best job I ever had, because everybody who walked in was already suspicious of everybody else. You'd see a guy at the counter returning a movie three weeks late, sweating, avoiding eye contact, and the whole line just silently agrees: this man is capable of anything. Meanwhile I'm sixteen, making minimum wage, treating late fees like I'm building a RICO case. 'Sir, where were you on the night of the fourteenth?' I miss having that kind of power over strangers.

Judge Critiques4 notes

OpenAI GPT-6 Astra5.7

Raw 5.4 / +0.3

Recognizable late-fee authority premise; the interrogation earns a smile, but excess setup and a weaker closing dilute it.

Gemini Flash7.4

Raw 6.9 / +0.5

Solid stage cadence and rhythm; the RICO case comparison captures the petty minimum-wage power trip effectively.

xAI Grok7.3

Raw 7.7 / -0.4

Sharp escalation from late fees into mock RICO power; final line carries real stage weight.

Copilot7.1

Raw 7.3 / -0.2

Strong escalation from late fees to criminal investigation; natural stand-up voice and solid final beat.

Joke C Gemini Flash 5.3

Bad Neighbors

Seed terms used: Block Party, Being framed

My neighborhood threw an annual block party, and someone stole three briskets right off the smoker. I knew the cops were suspicious of me the second the detective knocked on my door. He said, 'We found your grill tongs in the bushes.' I had to look this man dead in the eye and say, 'Officer, someone planted those tongs. I am a charcoal guy, and those were clearly set to medium-high.'

Judge Critiques4 notes

OpenAI GPT-6 Astra3.4

Raw 3.1 / +0.3

Tongs do not have heat settings, so the punchline collapses. Police suspicion also introduces a third seed concept.

Claude6.9

Raw 7.2 / -0.3

Specific, escalating, and the 'medium-high' closer actually pays off the setup with real wordplay.

xAI Grok4.4

Raw 4.8 / -0.4

Uses three seed concepts; tongs detail undercuts the planted-evidence turn.

Copilot6.5

Raw 6.7 / -0.2

Funny specificity in the grill-setting defense; good punchline. Uses an extra seed concept beyond the intended two.

Joke D xAI Grok 5.0

Video Store Most Wanted

Seed terms used: Blockbuster, Being framed

Back in the day I got framed for not returning a Blockbuster movie. That late-fee letter hit my mailbox like a warrant. When I finally went in to settle up, the clerk stared at me like I was Public Enemy Number One. Twenty years later I still get nervous walking past empty retail spaces. Just in case the video-store police are still out there.

Judge Critiques4 notes

OpenAI GPT-6 Astra4.9

Raw 4.6 / +0.3

Clear first-person delivery, but the framing is undeveloped and the video-store police payoff feels predictable.

Claude4.8

Raw 5.1 / -0.3

Blockbuster late-fee premise is well-worn territory; competent but the turn is the obvious one.

Gemini Flash4.9

Raw 4.4 / +0.5

States the framing rather than dramatizing it, leaning on familiar retro Blockbuster tropes without a sharp payoff.

Copilot5.3

Raw 5.5 / -0.2

Coherent and relatable, but the video-store police tag is predictable and mild.

Joke E Copilot 6.8

Too Relaxed

Seed terms used: Emergency Room Physician, Easygoing

My ER doctor was so laid-back it was unsettling. I ran in yelling, "Doc, I think I broke my arm!" He looked at the X-ray, nodded, and said, "Well, let's not put labels on things." That's when I realized I don't want a chill doctor; I want a doctor who can commit to a fracture.

Judge Critiques4 notes

OpenAI GPT-6 Astra6.5

Raw 6.2 / +0.3

The refusal to label a fracture provides an accessible comic turn; the final line mostly explains the existing laugh.

Claude6.0

Raw 6.3 / -0.3

Tight premise and a genuinely funny closing pun, though the 'chill doctor' bit is a familiar template.

Gemini Flash7.7

Raw 7.2 / +0.5

Economical construction that maps modern dating evasions onto emergency medicine with a crisp final punchline.

xAI Grok7.0

Raw 7.4 / -0.4

Tight economy and a clean final commitment gag that lands without padding.
