Gotta be careful with this one. As with most things, it's about being in the right company and doing it at the right time, and if you're not sure, the answer is no, it's not a good idea. In the company of close enough friends, though, it's not that big a deal; just make sure the boss, other employees, or clients aren't within earshot. PS. It should be noted that, as unfair as it is, a woman could get away with this far more easily than a man could. For the guys, you might want to watch what you say around the wrong person, because they could slap you with a lawsuit faster than you can say sexual harassment. It's not fair, but it seems that's the way it goes.
