FYI to single guys.

If you're talking to a girl at a bar and her guy friend taps on you shoulder and says "Dude... she's a guy".

You should either:

A. Assume she's really a guy and walk away.
B. Assume she really doesn't like you.

The only way B would ever happen was if you were a moron and didn't take the hint in the first place.

Of course if you're a moron you're probably not smart enough to formulate either A or B at which point you don't deserve to reproduce anyway.

There needs to be a Darwin award for people who take themselves out of the gene pool just by not reproducing.
