Oh, you posting it isn't what bothered me, it's the concept that bothers me.
"Uh, I can't seem to get as much stinky air as the other one with the different diameter, but at least it's long enough this time to get through to the other side of the yicky water without having to lean almost all the way in. Daddy."
Oh, and I've seen worse. There's another forum that I'm on that has several sensitive women on it, and some of the guys go out of their way to be as gross as possible, trying to offend their sensibilities.
So, no problem.
My sense of humor is pretty bad, too. Are you familiar with Lenore, the Cute Little Dead Girl? The invention, in particular, reminds me of "The Thing What Came from the Poopy Chair".
