I straight-up lied to children for YEARS just to avoid an uncomfortable joke..
I taught Latin chant for a few years at a posh Catholic middle school. My first semester there was rough as I was a fresh music teacher out of college and really didn't know how to handle 8th grade boys. One of the first chants the priest asked me to teach was "Panis Angelicus" and I died internally because I KNEW those 8th grade boys were going to make penis jokes given how close "panis" was to "penis" ...and I had no idea how to handle it without blushing myself (I know, I know - I'm a much more seasoned teacher now!).
So I lied and taught them via rote ("repeat after me") not letting them see the words for weeks, pronouncing it without the "s" so it was just "pani" ...and then when I finally handed out the music, I mentioned very casually off hand that some words in Latin don't pronounce the "s" at the end, now are you ready?, 1 2 3 sing!
When we performed it (with the sheet music in front of them, another strategic choice), inevitably a couple kids accidentally added the "s" in, creating the illusion of correct pronunciation.
100% would do again.
