The best story I ever heard was from back in the 80's.
Motley Crue bass player Nikki Sixx and drummer Tommy Lee held a contest to see who could go the longest without washing, showering or bathing in any way, yet still be able to sleep with groupies without them being ill or bailing out. For two months, they had "nightly groupie sex" with up to four girls each, until finally some groupie, who was giving Nikki head, became violently ill and barfed all over him. It later became known as "The Spaghetti Incident" because the unfortunate groupie had eaten pasta beforehand.
