Stan is the DM.
Eric wants to play the Wizard, who is also a Ninja and a Paladin. Half dragon, half drow.
Butters wants to play the Wizard, but Eric says he already is the Wizard. Butters says then he'll play the Sorcerer, but Eric says no, it's too close to a Wizard. So Butters says Rogue, but that's too close to a Ninja, so Butters plays a Barbarian. A Halfling Barbarian.
Kyle says whatever, and gets stuck with the cleric. Eric complains that Jews can't play clerics. Ike also wants to play, but Eric says Ike is too young to play, and wouldn't understand their game for . . . whatever that geeky term is for long-time players from the D&D short comedy movie.
Kenny plays the Rogue, who is immediately caught in a trap, and rolls a 1 to save. As Kyle is saying, "You bas . . . " Stan says, "Wait, wait" and rolls something behind the screen, and says Kenny survived anyhow, due to the fact that secretly, Kenny's character was protected by the old man back at the tavern, who cast a "Deus Ex Machina" spell on him. Eric says "Kewl" and seems impressed, then reminds Stan that his character talked to the old man too, and the old man liked him better.
Chef says, "Now chil'run, that game may be all well and good when you're little chil'run like yourselves, but you gotta stop playing when you get past middle school, or you won't get no sweet woman love. You could end up like Mr. Garrison, talking to a sock puppet of a dragon or something."
