The For Unlawful Carnal Knowledge Tour (often abbreviated as the F.U.C.K. Tour or simply The Fuck Tour) was a concert tour by American rock band Van Halen in support of their studio album For Unlawful Carnal Knowledge. It was one of the band's longer tours, divided into 99 dates. It featured shows in Hawaii and Mexico, places Van Halen rarely played in their history. Sammy Hagar chose Alice in Chains to be the opening act after seeing the music video for their hit single "Man In The Box" on MTV.
