Sheldon?
From “When Harry Met Sally”:
Harry: Shel. Sheldon? No, no. You did not have great sex with Sheldon.
Sally: I did too.
Harry: No, you didn’t. A Sheldon can do your income taxes. If you need a root canal, Sheldon’s your man, but humpin’ and pumpin’ is not Sheldon’s strong suit. It’s the name. ‘Do it to me, Sheldon.’ ‘You’re an animal, Sheldon.’ ‘Ride me, big Sheldon.’ It doesn’t work.
