My roommate, who grew up in Michigan, told me about a theater game that she learned at a theater camp.
The game is called Kitty Wants A Corner. To play it, you stand in a circle with one person in the middle and the goal is to not be in the middle (it’s kind of like being “it”). The person in the middle goes to each person in the circle and stands in front of them, looks them in the eye, and says “Kitty Wants a Corner” as though they’re the kitten and want a spot to sit. You don’t want to give up your space in the circle, so you’ll say “No, go ask my neighbor” so the person moves to the next person in the circle and says the same thing. In the meantime, other people in the circle, mostly people behind the person who is it, will make eye contact with each other, and silently agree to switch places while the person in the middle is distracted. The person in the middle can intercept the switch and try to get a spot in the circle, and the person who didn’t make it all the way has to be in the center.
My roommate learned it at camp in Michigan, so she was surprised when they played it at her improv class at Second City in Hollywood. She thought it was strange because the person teaching the game in Los Angeles had no connection to Michigan. The informant had also only ever played the game at the camp before, it wasn’t part of her high school theater program at all. It’s likely that this game spread through actors moving around (which is common) since I have also heard of/played variations of this game, but it wasn’t exactly the same thing. If the game was an official “theater game” it would be the same everywhere, but there’s variation in how it’s played in different places.
