It's just that hearing memento
pronounced "momento" is a pet peeve of mine. It really grates on me, and it's rooted in the completely wrong assumption that the word is somehow related to "moment." It isn't. Not even slightly. It's from the same root as mem
ber, etc. So making a joke based on the exact misconception I'm trying to correct
just makes it harder to get that across. So no, I'm not inclined to be amused by that.
