I was watching a repeat of Will & Grace (which I don't usually watch) last night. Grace was obsessed with eavesdropping on her neighbors - the wife was having several affairs while her Doctor husband was at work. Grace said to Will, "Her husband is out saving lives and she's sleeping around!" Will replied, "He's a dermatologist - he's not saving lives, he's popping pimples!" This looks like it was directly lifted from the Seinfeld episode where Jerry dates the "pimple popper M.D."
