Ok this idiot of the first order is invited for a game of golf for the first time, while in another country.He's totally enamoured with the golf ball because he's never seen anything like it before so he carries like, 30 of them back home to give away as souveniers.While passing through the customs on his way back, the customs officer who's perhaps a bigger idiot than this guy, notices his pockets bulging with all these golf balls and can't figure it out. So he asks our man, "What the hell is all this?!"To which he replies, "Oh they're just golf balls." So the customs officer goes, "Oh oh! You mean like tennis elbow?"
