When the folds (Wrinkles) in a scrotum resembles that of a smiling face. Eyes and Mouth are required, nose is preferred, but not required. THE SACK MUST BE HAPPY!!! Must be declared by a spectator, not the one whom the sack belongs to!
If the "FACE" is hairy, 'Ball Bunyan That Smiles Back' may be decalred!
So Jane made me sit next to her hot friend lisa then sat on the other side of me so I was in the middle, it was the straw that stroked the camel's sack!
