Here are some good caddie jokes from the Charlotte Observer
Golfer:"I think I'll drown myself in the lake" Caddie:"Think you can keep your head down that long?
Golfer:"Do you think I can get there with a five-iron?"
Caddie: "Eventually."
Golfer: "You've got to be the worst caddie in the world." Caddie: "I don't think so, sir. That would be too much of a coincidence."
Golfer:"How do you like my game?" Caddie: " I prefer golf."
