Okay, empathy is not your thing so I'll help.

A man's wife was in a terrible car accident and as she dies on the operating room table, some assclown dressed as the grim reaper walks up and stands there. Do you truly believe anyone is going to "have fun and laugh" in that scenario?

I'm not saying you can't laugh at the guy, but for fuck's sake hop out of your own head for a minute and consider other perspectives.

This is what I meant with my first comment. In a situation where there was no potential for harm, like in a sitcom, this is hilarious. In real life, it is not funny, because there's that risk of harm.
