I wrote a skit to promote a play I was putting on at church. It was your standard Jeopardy!-with-stupid-contestant skit, my fallback when I can't think of any more clever way to convey a bunch of dry information (date, time, etc., of play) in a short period of time. Anyway, at the very end, my dumb contestant, having frustrated the host (me), asks, "When do I get to play Plinko?" It got a fair amount of laughter, though not as much as I was expecting, and I was surprised at how many people afterward asked me what Plinko is. I figured if there's one TPIR game that's universally known, Plinko is it. Usually they recognized it once I gave them a brief description, but it was still surprising to me how many didn't recognize the name.
