A: I'm doing some volunteer work at XYZ Baptist Church this weekend (that wasn't the actual church name, but there are so many Baptist churches here, I don't really keep track of who's who).
Me: You're Catholic, isn't it a mortal sin to associate with Baptists? (of course, I said this in front of a close friend of both of ours, who is Baptist).
A: Hell, I don't care, I'm probably going to be excommunicated anyway.
Me: What'd you do, bang your sister?
A: No, I'm getting a divorce.
(more awkward silence)
Me: Well, who HASN'T the Catholic church excommunicated? They did the same thing to my ancestors 500 years ago.
A: You have a point.
