S2E1: the group is held captive and are threatened with rape. They escape. In the same episode, a man is raped and killed off-screen. S2E3: a very young character/child is described as 'a violent and sexually deranged being from the fourth dimension'. This is played for laughs. S3E5: a joke is made about the moon being a 'vanilla rapist.' In the same episode, a decapitated (but still living and conscious) head is raped by a non-human creature. S3E6: a homeless person admits he had planned to rape a key character. During the same episode, a character also makes similar comments towards a different character. Worthy of note: in the Book of Boosh it is mentioned that the hobbies of the Hitcher character include 'playing cards and raping.'
