T.G.I.F.

The only known comic.

T.G.I.F. was a comic drawn by Rowley Jefferson for Greg's Newspaper, The Neigbourhood Tattler. The one time it was seen in Cabin Fever, it showed a man running around in his boxer shorts. He meets a cop who asks him why he's doing that. The man says, "It's Friday!" Then they both go running of in their underwear.
