If you need a quick laugh, check out this video called "Dumb as Stick". It's a dog trying DESPERATELY to take a stick home with him. But it's about five feet long, and the gate he's trying to go through is only three feet wide.

His owner finally helps him at 1:13

My yellow lab used to do this all the time. It's funny because you can actually see them trying...and failing...to figure out how they're going to make it work.
