Penny Arcade is a web comic written by Mike Krahulik and Jerry Holkins. The strip features their cartoon alter egos John Gabriel (a.k.a. Gabe) and Tycho Brahe, respectively, who spend much of their time time playing computer games and commenting on them. A good deal of the humour of this strip revolves around Internet subculture and video games, and often features in-jokes that are explained by the news posts that accompany each comic. One of the most popular aspects of this strip is the signature drawing style of the artist, Mike Krahulik (Gabe). Penny Arcade regularly features profanity and violence, and can easily be considered offensive to those unused to such elements. The first comic strip appeared on November 18, 1998.

There is little continuity on Penny Arcade, owing to the writers' dislike for the concept. They have been quoted as describing it as the "dreaded continuity". A character who dies a horrible, violent death in one strip will come back the next perfectly whole. There is also little realism in Penny Arcade. All manner of creatures have been known to drop in, from zombies to a talking DivX player, and all manner of strange events have been known to take place.
