Give Me Back My Son

Via Will Hines, a terribly delightful improv warmup game that pays tribute to Mel Gibson:

(Warning: Video contains a lot of overacting and yelling.)

Will explains:

So the warm-up works like this: everyone stands in a circle except one in the middle. That person approaches someone in the outer circle and demands "Give me back my son!" with complete dramatic commitment -- inspired by Mel Gibson's over-dramatic delivery in the movie Ransom -- trying to get the outer circle person to laugh. It's to practice emotional commitment and also making your teammates laugh -- two valuable skills.
