Insanity is NOT a contagen... (Part I)

An actuall conversation had by a friend and I...

Me: Hello

Friend #1: yellow

Me: jello

Friend #1: mellow

Me: fellow

Friend #1: chello

Me: hmm. chello needs to come before fellow-

Friend: eh?

Me: ...for it to be a sentence, of course.

Friend: ... this was a very, very boring game.

Ha. You started it.
