Scottish caddy:

 

During his vacation in Victoria, BC,  Liberal leader Bob Rae was slicing off the tee on every hole.  He asked his Scottish caddie if he noticed any obvious reasons for his poor tee shots, to which the caddie replied:

"Aye, there's a piece of shyt on the end of yer driver."

Rae picked up his driver and cleaned the club face, at which point the caddie said:

"Nooo, the other end."
