With no warning my mom sims died of laughter. I am so mad.

This happened too me :D I find it funny now but at the time I went away from the screen and cane back and a message popped up saying my sim was dying of laughter!! I tried getting him to stop watching comedy but he was a goofball, had the hysterical moodlet so he had no luck :| He just got married and was a father oof.
