Would you like to win the lottery? I would believe you have almost as much of a chance of getting an std from a urinal. If you do, let me know, I will need to see if I was a winner in the drawing last night.

Seriously speaking, in the 1960's they said it was possible, but highly unlikely. If students appeared in the doctor's office with an std and blamed it on the urinal, the doctor, after he stopped laughing, gave us a shot, asked us who we were with, and requested them to come in for a check up. 99% of the time, the partner also had an std.

Bottomline, not likely.
