Peter: Woah! Is that really the blood of Christ?
Peter: Man, that guy must have been wasted 24 hours a day, huh?
A number of my friends do find the above offensive, but I just think it’s hilarious. It doesn’t bother me too much for a few reasons:
1) Peter Griffin is an idiot and has misunderstandings like this all the time
2) It actually does reaffirm the truth about the Eucharist: it truly is Jesus, it’s not often you find affirmation of Catholic doctrine on TV (although the Family Guy isn’t bad on this front, considering the nature of the show)
It’s so funny, I seem to recall they actually used it in separate episodes.
