There have been times I've been put in the same sitch (sic). Just don't make it a big deal, and most chicks won't care.
If you start getting looks, though (mostly happens with older lady-types), then the key to not looking like an asshole is this: keep a straight face. No matter how funny their reaction might be, you'll only look like a jerk idiot if you make a joke out of it.
Oh, and don't listen to Vince--I hear he’s a real pansy.
