The doctor is brought into a room with a gorgeous blonde, brunette, and redhead, and asked which one he would most like to sleep with. The Doctor replies, "I my professional experience, blondes tend to be more sensitive to stimulation, so I would do the blonde." They repeat the experiment with the business man, and he replies, "In my professional experience, brunettes tend to be more assertive, and that's what I want in a lover, so I'd do the brunette."
