"Ya Got Trouble" is a patter song by Meredith Willson from the 1957 Broadway musical The Music Man and its subsequent film adaptations in 1962 and 2003.
The song is performed by con man "Professor" Harold Hill, posing as a bandleader and traveling salesman as he attempts to scam a small Town in Iowa. In order to create demand for his musical instruments, he creates a moral panic around a new pool table in the town's billiard hall and the slippery slope that, without proper supervision, would lead their children to corruption.
Willson considered eliminating a long piece of dialogue from his draft of The Music Man about the serious trouble facing River City parents. However, he realized it sounded like a lyric and transformed it into "Ya Got Trouble".
The song is sometimes listed as "(Ya Got) Trouble". The original Broadway cast album lists the song title as "Trouble", both on the record jacket and label. "You Got Trouble" is a common misspelling of the song title.
