If this was the biggest thing in your day to be concerned about, give thanks to God for your peaceful life. While you’re at it, you can pray (a) that the priest’s health is OK since he was out having a medical check and (b) that he develops a less groanworthy sense of humor.
Seriously, I can see turning to your husband and saying “oh what a dreadful joke, reminds me of something your Uncle Pete would tell at Thanksgiving dinner” and then moving on with your day. I can’t see why a 30-second joke would merit a whole forum thread to gather others’ opinions. Seems incredibly petty like most of the threads about “the priest did this or that thing, what do you think?” I’m beginning to think there should be a whole forum just for people to carp about little things priests do.
