In an interview with Uncut magazine, Lars Ulrich of Metallica saysfans used to ask the band to fuck their girlfriends.

In the early days in America back in the mid-’80s, people would often ask us to fuck their girlfriend,” Ulrich recalled. “The first time it happened to me, we were opening for Ozzy [Osbourne] in 1986 and I was slightly taken aback. But you realise people were serious and you say to yourself, ‘So now I’m fucking your girlfriend, are you round the corner, whacking off? Are You taking pictures? Where do you fit into all this?’
