Sinbad appears briefly in Good Burger 2, reprising his role in the original Nickelodeon teen comedy series. Good Burger 2 was a surprise when it was first announced, with many fans of the original 90s series delighted at the unexpected return to the "Good Burger" ("Home of the Good Burger, can I take your order?"). The original Good Burger sketch was one of the funniest on All That, largely thanks to the two-star characters and best friends, Dexter (Kenan Thompson) and Ed (Kel Mitchell), who return for the sequel set 26 years after the first movie.
