A few years ago I got into Bobby Van's Make Me Laugh and watched a few episodes on Youtube. I also enjoyed the Comedy Central version and am surprised it hasn't been revived since, outside of a proposed version about a decade ago. With so many comics finding fame through social media, it's not like there's a shortage of funny people willing to work for scale and get their name out there, just like Bob Saget, Howie Mandel, Patton Oswalt, and so many others did back in the day.
Adjust the scoring to $5 for every second you don't laugh, and of course the game ends when you crack. Three contestants, and the high scorer comes back for the "tag team" bonus round that Comedy Central used. If you last a minute without laughing, you win a trip and let's say $5,000. Otherwise, $10 for every second you didn't laugh.
