Drake & Josh episode The Bet
March 14, 2004
In the first episode of season 2 (Episode #7), Josh is often seen playing videogames, and the characters' lines suggest that he's playing a Mario-like game. Specifically, while playing on a Game Boy Advance SP he says "Yeah, look out red turtle shell!" then in a later scene, while playing on a home console Drake tells him "Jump the mushroom!" and he replies "I'll jump the mushroom when it's mushroom-jumping time!"
The creators of Drake & Josh didn't have any right over Nintendo's Mario, but they only included a subtle reference to the games.
