Dave is the owner of XXX X, a dive bar that is the only place near Langley Falls to get a keg of OG 4Loko in "Steve, Snot, and the Quest for the Og 4Loko".
Steve finds out that if he can get into Vince Chung's party, a girl will give him a hand job. Vince agrees to let him in, provided he can get a hold of a keg of OG 4Loco, which is strictly kept under lock and key at XXX X. Unable to get Roger to directly help them, he and Snot go through his wardrobe and find clothing and ID's, which to their surprise, actually work for them in fooling the bar patrons. However, they find out that Dave is away at a wedding with the key. Getting a ride with Principal Lewis, they find themselves near the Ramada where the wedding is taking place. Unfortunately, Dave is kicked out and Steve and Snot's personas get them in trouble as well, forcing them to flee in a taxi in which Roger is driving as a 'Khol's Cash Cab'. Forced to play for Khol's Cash, they end up losing and get kicked out in a bad part of Chimdale where they spot Dave, vomiting before passing out. Entering his apartment after finding only a single key, they locate the keg.
