A smattering of lyrics, crippling neuroses, and manatee jokes.
Wrestlers trust each other, full stop. It just doesn’t work if you don’t. You have to trust that the other person is going to take a hit when you give it, to make your moves look awesome, to listen when you’re calling the match (i.e. making it up as you go and telling each other what moves you’re about to do) and to not physically hurt you for real. If you don’t trust the other person in ring, you’ll be secretly trying to protect yourself, trying to control the match, and you won’t be fully present, which means you could actually hurt yourself or them or a bystander.
If you don’t trust your fellow players on the improv stage, you will be too busy protecting yourself from looking silly to do a good scene, and you’ll hurt the work. Or your scene partner. Trust that you will both make the other look good, that you will listen to each other, and that you will give each other a great time.
This is a really great comparison.
I think it was Sylvester Stallone that said wrestlers are the best improv workers around. I’ve always agreed.
