a movie

In which Oliver demonstrates:

a roll-over

a high-center

a smile

a bit of heavy breathing

and

"sid walking"

"Sid walking" is at the end of the flick. But what is it?

If you ever saw the movie 'Ice Age' there's a character named Sid (the Sloth). When he tries to get comfortable on night on a bed of rock, his head is an anchor point while his feet "walk" around the rock trying to find a comfy position.

It is a bit long- but I think the grandparent quotient is pretty high:)
