Dave's style

[Princeton]

Through my time spent on the forum, I have picked up on what the Muppeteers' performing styles are. Here's what I've learned:

Jim- turns his characters' heads to the side when they're singing.
Jerry- skips syallables.
Richard- double takes.
Frank(I picked up on this one myself)- his characters scurry when they walk.

My question is, what is Dave's style of performing?
