The legendary Gus Johnson made a hilarious mistake while doing the play-by-play for the TCU-Kansas State game on Saturday night, and it wasn’t even caused by overexcitement.

Johnson, who is known for his enthusiastic calls, accidentally confused Ron Burgundy of “Anchorman” with Ron Jeremy, the porn star. The flub happened when Fox showed this fan’s sign on TV.

Gus Johnson just called Ron Burgundy, "Ron Jeremy" ???????????? #tcu #ksu #foxsports
