It may have been the same episode as this, or maybe this was a 2-parter, but I saw another Simpsons show recently that was pretty funny, about religion. Homer had converted to Catholicism, and it caused a big ruckus. Then Bart, of all people, told everybody to get a grip and stop fighting because they were all christians. At the end, there was a future shot of 2 armies getting ready to attack each other, fighting over what Saint Bart meant to them 1,000 years later. Funny stuff. Another funny moment was when Flanders agreed to shake hands with a Catholic, then starts muttering to himself "remember to get hand reblessed, remember to get hand reblessed".
My wife was in the kitchen, and I called her in to see it cause I thought it was so funny... I explained the background as she walked in: "Homer converted to a different religion, and its causing all kinds of funny trouble, you gotta see this". My wife: Changing religion in a marriage? Oh, that's never good. Me (deadpan): Tell me about it.
She either chose to ignore it, or it flew right over her head, but I couldn't help but think how ironic it was that she could recognize that in a mere cartoon show, but apparently not about our real life, what with her studying with witnesses. *sigh*
