A rapist and a little girl walk into the woods.  The little girl says she's scared. The rapist goes, "why are you scared? I'm the one that's gotta walk back alone"
Do you have a reason for making jokes about rape victims?
I do not have any problems with rape. The shirt is fun..
Children being the victim of rapes and murders is no laughing matter, and nobody should make jokes about it.  You never know what kind of trauma someone in the audience might have had in their life.
