What is the Golf ball and hose joke?

Doug was a single guy. He had a good job, he was fun to be around, and wasn’t bad looking. He was in his early 30’s and never married. He went through girlfriend after girlfriend and always seemed to break up with every girl at about the three week mark in the relationship.

One evening Doug was at his local bar and the the bartender asks him why he breaks up with every girlfriend at the end of the third week. Doug says “well I just won’t marry a woman unless she can suck a golf ball through a garden hose. I know it’s a high standard, but I promised myself that I wouldn’t accept anything less than that one trait in a woman.”

A few years go by and a few dozen girlfriends later the bartender hasn’t seen Doug in the bar for a while. He asks around and none of the guys he hangs out with had seen him for a couple of months. Then the local doctor walks in and the bartender worried about Doug asks if he knew anything about where he was. The doctor says “Some girl sucked Doug’s testicles through his pee-hole……The wedding is set for june”.
