Got an itch?

Two guys are talking when the one notices his buddy keeps scrathing at his croch and its becoming annoying so his buddy finally says "Dude whats wrong with you?" His buddy kind of leans in and says softly "I was doing this chick and i think i got something from her" His buddy nodded understanding now "That sucks man no wonder you upset" "No thats not it, i dont know who i got it from" "What do you mean?" "All them damn sheep look the same"
