He / Him
It's one I adopted into my 3rd Grade classroom to help my students self-moderate. When they ask me questions about what they're allowed to write about or draw (especially in regards to violence), I just say, "Would you show it to my sweet old granny?" It works a lot better than having a bunch of explicit rules about what they can or cannot draw.Well, the Grandma Rule has always been about how coarse you are supposed to be - use of foul language, sexual innuendo, and such. But, yeah, you'd think that between the Grandma Rule and Wheaton's Law, it'd be covered, but... no.
