In the game Kingdom of Loathing when one kills a Goth Giant there is a chance that a Warm Subject Gift Card will drop. Warm Subject appears to be a parody of the retail store Hot Topic and the goth-like apparel they deal in.
Turtle Tamer: Hey, have you got any meat?
Accordian Thief: nah... oh crap! I just remembered I have like five Warm Subject Gift Cards in my inventory!
