Let's play a game. A very easy one at that: All you have to do is pick any title from an episode from the show and remove any letter, at an attempt to create a pun. Then, you make a poorly drawn representation of that pun. Don't say the name of the ep until someone gets it right.
For an exemple of movies, you could do "Moan", "A Bus Life", "Wall", "Finding Emo", Etc.
Good luck, and be creative!
