I'll say again, people tell tasteless jokes for a million reasons. Sometimes it is to release pain through laughter rather than crying or anger. Sometimes it is to make political or social commentary. Sometimes it is to be just plain mean and vindictive. But in the history of comedy, tasteless humor has a long, even honored tradition. In fact, the "greatest joke ever," called "The Aristocrats" is nothing but vile, degrading and tasteless. In fact, the more disgusting you can make the joke, the more honored you are.
Is it telling of a person's character? Sure it is. They are many things that are beneath us as human beings and we do them anyway. BTW, J.J. you're not going to hell for the jokes you tell. You're going to hell for telling them badly. See. That's an example of a tasteless joke that is beneath me. And I told it anyway. With that in mind then...
Did you know Curt Cobain's eyes were blue? When the shotgun went off one blew this way and the other blew that way.
Did you know Princess Grace (Grace Kelly) was on the radio when she died? And on the steering wheel and on the seat covers and on the dashboard...
Do you know how Helen Keller burned her face? She answered the waffle iron.
Do you know how she burned the other side of her face? He called back.
Just reminding one and all that the series of M.J. jokes is nothing new. If you laugh at someone falling down, farting, peeing on something/someone, belching, vomiting, snot, etc. then you're part of this crowd.
