Rupert Everett's entrance...
According to a film co-worker, Rupert Everett tells an amusing story about going to the doctor with a nasty rash. He hadn't gone to his usual doctor because he was quite embarrassed about the location. After a couple of complicated and long-winded attempts at explaining, he blurted out that it was around about "his rear entrance."
The elderly and very well-spoken doctor peered over his glasses at him and said "Most males refer to that as a rear exit, Mr. Everett, but I think I know where you mean"
Thanks to Popbitch. Methinks an urban legend but funny all the same.
