How bout when the Tiger was turning its turret around and it gets stuck on the tree. That always make me laugh.

A real Tiger would have snapped the tree in half or simply uprooted it!
My favorite character was Oddball.
Oddball: "Why don't you knock it off with them negative waves? Why don't you dig how beautiful it is out here? Why don't you say something righteous and hopeful for a change?"
