The Irish Golf Caddy

A Golfer has been slicing off the tee on every hole.
He asks his Irish caddy if he has noticed any obvious reasons for his poor
tee shots, to which the caddy replies:

"Aye, there's a piece of shyt on the end of your driver. "
The Golfer picks up his driver and cleans the club face, at which point
the caddy says:

"No, the other end."
