On Christmas morning, a cop on horseback sits at a traffic light next to a kid on a shiny new bike.

The cop says to the kid, "Nice bike you got there. Did Santa bring that to you?"

The kid says, "Yeah."

The cop says, "Well, next year, tell Santa to put a tail light on that bike" and issues the kid a £20 bicycle violation ticket.

The kid takes the ticket and says, "By the way, that's a nice horse you got there. Did Santa bring that to you?"

Humouring the kid, the cop says, "Yeah, he sure did."

The kid says, "Well, next year tell Santa to put the dick underneath the horse instead of on top."
