What about toilet humor?

I like most of the humours.I am enjoying all fun messages from my friends.Here is a joke. Blood Circulation: A teacher was giving a lesson on the circulation of blood. Trying to make the matter clearer, he said: "Now class, if I stood on my head, the blood as you know, would run into it and I should turn red in the face." "Yes, sir," the class said. "Then why is it that while I am standing upright in an ordinary position the blood doesn't run into my feet?" A class member shouted, "'Cause your feet ain't empty." Thanks

There are different kinds of humor for different people. Some people like any kind of humor. Some have set a boundary for humor. I like humorous stories that make me laugh as long as they are not below the belt. Even in toilet, you can read humorous writings like these: "You are now sitting on the throne of comfort, don't make funny faces." That made me laugh when I first read it inside the toilet.
