Does it hurt to poop out gum?

Well, although I personally have swallowed gum (and then, I assume have excreted it), I have never had any pain in doing so. Others may have different experiences, however, and the person who answered the question before me had clearly had some painful experience with the matter, but I myself cannot testify to having experienced any pain.

However, from what I've heard at least, swallowing gum is not a good idea. It has the potential to bung up your insides, which may cause severe damage. Having said that, it is not a good idea to spit it onto pavements (side-walks for the Americans), or public monuments either.
