Cheese Racer

Origin: This little joke originated at the "Bob and George" forums. To "blend in with the crowd", H Hog attempted to make a megaman-related sprite comic, planning to eventually have "Dolby Surround" make an appearance, this being his Megaman-based character. The first comic has since been lost forever, but it was the origin of the Cheesewedge Mobile - take the wheels of a yellow car that appeared in a Megaman game, then crudely draw a cheesewedge with a hole, a steering wheel and an exhaust pipe on it.
Voila.
The back of the car seemed somewhat empty, so H Hog slightly tweaked the H Met sprite Neo made for him, then added it to the back of the car, as a cheese wedge would of course require machinery to run correctly.

Cheese Racer re-appeared eventually in H Hog's "Random Signature Chatter", a periodically updated feature that had H Hog utter some random quote of the moment.
