Had a lipoma on my back in my twenties which wasn't a problem. Benign and painless. Until it got infected then it was pretty inconvenient, painful even when rubbing against clothing. So I went to a doctor in a Dutch backwater where I was working who thought the best way to remove it was to use a cooling spray and then cut the top off and squeeze the infected fatty puss out. Fuck me, that was painful. The spray didn't work, of course, and it was like having a bullet removed without any anaesthetic (I imagine).
Still, the girls were impressed when I told them the resulting hole in my back was a bullet hole. "Dined out" on that for a good while.
