Yeah, we're on to something here. It's the seldom discussed sensual side of a shaved head and what it has, or does, for some people.

Since it's almost Halloween, maybe now is a time to talk about the "dark side".

OK, how should I couch this delicate subject? OK, here it is in a nut shell, some people just get off on the sly effect. It's kind of like fermones, and hormones, and the other moans.
OK, I digressed. But I think you might get the idea. Bill's demonstrated that he is a hot sly guy (to some women), and a woman picked up on it, and almost picked him up in the process (or could have gotten him in serious "do-do" with the young ladie's main squeeze (hubby)).
Of course there are a number of other possible motives playing in here. Maybe the woman wanted her husband jealous. We, as mortal men, may never know all the reasoning (?) that goes on in a woman's head. Suffice to say, we just have to enjoy them when we can. Otherwise, just hold on to the rollercoaster, because it's an "E Ticket Ride" (the best that Disney has).
