"Smile, if you". what?????.....

Right down the street from the Hyatt, on the river walk, is a small recess between the buildings about two feet wide....we noticed a young, well-dressed guy, curled up inside it, holding a cardboard sign that said "Smile".
He had a tip cup, sitting next to his feet....as folks would smile real big at him, some of them would drop some coins or a dollar bill in his tip cup.
After they made their "donation", he would fold down the lower part of his cardboard sign to reveal the rest of his message, which was "SMILE....if you masturbate".
I gave him a dollar, just because of the big laugh he gave us. ;)
