This is one of the classical situations where you can only loose...

You're walking home from the bar, having had some beer, so you are already walking more relaxed than you should. At the far end of the street you see the siluette of a really hot girl, walking towards you. She get's closer, a really hot blonde, wow, is she hot. You start to realize it feels a bit windy down there. Damn, the zipper is open. You are confused. What do I do, do I close it, showing her that it was open? Do I hope she does not realize it and just walk past her? Whoaaaa. HELP! OK, just pretend everything is fine, hope that she does not see that you are wearing the most ugly shorts beneath, smile, do not be emberassed, behave normal. Damned. She has a big grin on her face. She saw it. Even after you tried to pull your shirt over it. Sinking into the ground. AAARGHHHHH. YOU LOOSE.
