Bi-Mon-Sci-Fi-Con

The Bi-Monthly Science Fiction Convention or Bi-Mon-Sci-Fi-Con is the bimonthly science fiction convention held in the town of Springfield. The commercials advertise it with two aliens and the tag line "Be there...and be square!"

The convention is a magnet for the geeks, dorks and nerds of Springfield, and Lisa Simpson is quite unsettled when she is greeted by several boys (Milhouse, Wendell, Üter) from her school while there. Other attendees have included Dr. Hibbert, Lenny Leonard, Carl Carlson, Mayor Quimby, Mark Hamill (himself) and Matt Groening (himself in cameo appearance).

It had been mentioned in two episodes of The Simpsons: Mayored to the Mob and My Big Fat Geek Wedding.

Comic Book Guy has been at Bi-Mon-Sci-Fi-Con in the two episodes where it is held, and oddly is also involved in a romance in both as well. The first time around he meets his female equivalent when sorting through boxes of, what else, comic books. However, when she requests that he comb the sweet tarts out of his beard, he dismisses her saying "Don't try to change me, baby." In the second episode, the Simpsons go to the convention to prevent him from going any further in his relationship with Edna Krabappel. Edna had previously been a runaway bride at her and Skinner's wedding.
