I had a boss once who, all else being equal, would generally hire tall and very rotund women. All else being equal is the key here...he did hire me, after all!

I frequent several coffee shops, and I notice that the staff at each has a distinct resemblance to their coworkers...Goths at one, slim dance-major types at another, and so forth - even though the same person (I think) is hiring for them all. I suspect it is because they tell their friends "hey, there's a vacancy where I work" more than anything else.
