And one of the funnest things was watching what they did before the director called action and after the director called cut. And they'd keep their hands in the puppets, they'd stay in character, and then they'd start goofing around with each other and be off of script, and it would get quite blue.

A puppet that starts to improvise badly is almost funnier than the puppet that's improvising well.
