Animals are usually somewhat smart, what with the whole "not being extinct by their own hand" thing. I mean, they don't jump into traffic on purpose, they don't usually gnaw on electric wiring and they don't accidentally mix up poisonous gasses. They're kinda smart like that.
But some of them still get stuck in whacky situations! How did they get there? What was their plan? How are they going to get out of there? All of these questions and more will remain unanswered because you will burst out laughing when you see them!
