There was a cop on his horse waiting to cross the road when Little Johnny, on his new shiny bike, stopped beside him.
"Nice bike," the cop said, "did Santa bring it to you?"
"Yep," Little Johnny said, "he sure did!"
The cop looked at the bike and, while handing the boy a $20 ticket, he said "Next year, tell Santa to put a license plate on the back of it."
To which Little Johnny replied, "nice horse you got their sir, did Santa bring it to you?" "Yea, He sure did," said the cop.
Looking up at the cop, with the most serious little boy tone, Johnny retorted, "Next year tell Santa to put the weiner(idiot or penis) underneath the horse instead of on top of it!" and peddled off down the road.
