In my current line of work, I deal with a lot of "women's groups", and am often the only male in attendance. I don't know if you have spent much time near groups of females, but the conversation often turns to "plumbing problems".
Now when guys talk about plumbing problems, it's usually about "sweating joints" or "threading the iron pipe" or "plunging for 20 minutes" or "snaking out the line". None of which are as interesting as they sound.
When women talk about plumbing problems, they are talking a little closer to home. THEIR plumbing. And the conversations usually devolve to horror stories involving childbirth.
This morning, I figured out how to trump their "greatest pain ever" stuff.
I told them that I had heard that a man getting kicked in the testicles experiences far more pain than a woman giving birth. And a proof, I said that a couple years after getting kicked in the nuts, he will NEVER tell his wife "You know dear, I think you should kick me in the balls again..."
