This is an old one I did way back in high school, I believe it was after a seminary lesson about the gift of tongues. I showed it to one of my friends, who asked me, "What does that mean?" I was a little taken aback because she been in the same classroom and had the same lesson with me. So I said, "Remember the lesson we just had about the gift of tongues?" She replied, "Oh! That's it! You totally misspelled the word 'tongue'!"
It's only taken me a couple of decades or so, but I've corrected that now.
