Is it OK with watch Family Guy with a 5-year old?

I actually agree with BRTD that most of the humor goes over the childs head, though I also think I'd at least discriminate based on the episodes. The earlier episodes might be alright, I suppose.

I definitely would not let an 9 year old watch it. A bunch of my second cousins and I once angered my mother's cousin because we were watching King of the Hill and our two youngest cousins (aged 7 and 5 at the time I think) were in the room.

Your mother's cousin is way over sheltering her kids if she thinks KotH is going to harm any person, ever.

Eh, I don't think she thinks it will harm them. I just don't think she likes her kids watching Adult Swim due to the ads that run in between shows, etc.
