Stuff on a Stick is the name of an unhealthy fast-food outlet at the O-Town Mall in O-Town. It features at the beginning of the episode Pranksters where Filburt is seen working there. The restaurant's signature dish is a rancid lump of deep fried ingredients with a flavoured sauce (chicken, fish & dessert). Rocko and Heffer both go to eat there on April Fools' Day specifically to play a prank on Filburt, much to his annoyance. Their motto is "Come stuff your face in our stuff".
It is later seen in the episode Seat to Stardom where Rocko and Heffer are eating before both try out for the Wedgie Boy underwear model role. It is unrevealed whether Filburt was working there at that time.
