Little Johnny was riding his brand new bike when a police officer on a horse motioned him to pull over.
Cop- 'Nice bike you've got there son. Did you get it for Christmas?'
Johnny- ' Yes sir. It's nice aint it?'
Cop- ' Yes it is, but next time you see Santa you need to tell him that bikes need a reflector on the back. Here is a $20 fine for your trouble!'
The cop started to ride off when Johnny pulled at his pants leg.
'By the way sir, nice horse you have there. Santa didn't happen to give that to you for Christmas did he?'
Cop- ' As a matter of fact, yes he did!'
Johnny- ' Well next time YOU see him be sure to tell him that the prick is supposed to go underneath the horse not on top.'
