After wiping away the tears from laughing so much, I figured out why this clip was so funny: he reminds me of MC Pee Pants from Aqua Teen Hunger Force. You better know what the hell I'm talking about. (I know the title of it makes the assumption that it really is MC Pee Pants, but I don't think it is.)
Yeah, Halloween was yesterday* but this is still funny too.
*I can't believe I didn't get any trick-or-treat'ers last night. I was ready for 'em with assload of candy. Your loss, kids.
