Where Do It go?

When I was in the hospital last year they weren't going to let me leave unless I had a bowel movement. I kept telling them I hadn't eaten in 3 days there was just nothing there. They insisted there had to be something.

I said "You know, I can eat a footlong Subway sandwich and I only get an inch and a half out. I don't know where it goes. I can't explain it, but if you don't let me eat something I will be here forever. Until the end of time."
So they gave me a cup of broth and an enema.
