Guy is always nervous about Little Billy and always attempts to tell him not to play on the street; it also fails every time by getting run over by Mario. Little Billy doesn't like Guy and just speaks in profanities saying things like "Dafuq?" and "Surprise mother f*cker".
History
In "Mario Goes Shopping", Guy tried to tell Little Billy not to play on the street (as he could get killed), but was then run over by Mario, the latter arriving at Wal-Mart. The duo later appeared at the near end of the video when Guy (now without his legs) shouted at Billy, "YOU COULD GET YOURSELF KILLED ON HERE!" when he was run over by Mario again. After this Billy said "SURPRISE MOTHERF**ER".
In "Mario for Hire.", it was pretty much the same, except in a different place and it only happened once. After Mario runs over Guy, the kart was then flying in the sky, with Mario (wearing sunglasses) and a dying Guy on board.
Appearances
The two had differing looks over the months between "Mario Goes Shopping" and "Mario for Hire.". In the former, Guy and Little Billy looked exactly like X and Baby Luigi, respectively. In the latter, they looked like Angry Indian Guy and Baby Mario this time (again, respectively).
