Ever since I saw the episode of South Park about Family Guy, I haven't really been able to get into it. Every episode still has probably five jokes that make me laugh out loud. For example, anytime they acknowledge that Brian's a dog (he always barks at black people), that kills me. But the "You think THAT's bad, remember when.... [random pop culture reference]" jokes don't do it for me.
But, it's easy viewing, and I still watch it pretty regularly.
I'm the same way....certain characters make me laugh:

I couldn't stop laughing when I saw that one.
