The part of that movie they really need to reference is Harry's speech about how unsexy the name Sheldon is:
Harry Burns: Shel? Sheldon? No, no, you did not have great sex with Sheldon.
Sally Albright: I did too.
Harry Burns: 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 Shel-don.' Doesn't work.
