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). ALF was also advertized to be an attendee at the convention. Even though Homer generally disliked nerds, he nonetheless went to the convention since it "beats work."
