Okay, this one is a little post modern:

A porn director gets done shooting a scene with a beautiful starlet and a well hung performer. The scene wraps and everyone goes their separate ways except the director who is packing up his gear. The starlet comes back on set once everyone is gone and starts flirting with the director, she gets his pants down only to discover his little secret. As he's having sex with her she keeps ridiculing him etc. The upside to this being of course that instead of the oft used phrase 'the guys in my past have been bigger' she is literally comparing him to someone that she had been with just a few minutes ago.
