Well, I still stand by my belief that diarrhea always follows constipation. The back-up of stool at the sphincter causes the stool at the back of the line to linger in the "blender" that is your stomach acid. Therefore, when the stool at the back of the line finally gets to the front of the line, it is in diarrhea form. It makes sense to me. My wife thinks I'm an idiot, though.
So how long are your large intestines when laid flat? 23 feet. That's a tad shy of the circumference of the Earth, but it's still pretty impressive. How long is the typical male's erection? 6 to 7 inches. Hey, I think about these things. Especially when you're sitting on the toilet for a little "me time", it makes sense to think about what's dangling in the toilet.
