Who killed Mickey Mouse?

This picture makes me chuckle every time I see it! He gets so excited every time he remembers that he can dress up like Mickey Mouse. This is his Halloween costume from last year and since the girls have oodles and oodles of dress up clothes and he doesn't have much to choose from, he gets his choice of Mickey Mouse, a dragon, a chicken or a knight. The girls' dress ups usually do a good job at hiding his options, so when he comes across them, he puts them on and he'll stay in them for a surprisingly long time! When I saw him like this, it just made me laugh to see him sleeping so seriously (as if anyone sleeps not seriously) in a Mickey Mouse costume. Just funny.
