Trust me, after a few fighting cock's down the hatch, most XX will gladly allow you to check to see if the hairy chest myth is true.
Razor - please ignore the above sentences. It is just to easy for a master like you, and there was no way to word it differently and still get the point across. LOL

"Cause it puts hair on your chest boy!"
