You guys might remember Garfield Minus Garfield, a tweak on Jim Davis' classic comic strip that swept the Internet a couple of years ago, but Snoopy and the gang have received the meme treatment as well. 3eanuts has noted that Charles Schulz was typically dependent on the last panel of the comic strip for his punchline, and with that panel removed, Peanuts is often morose and depressing.

Is is so amazing that jokes are strange if you leave out the punch line?
