"Ypto" is, itself, I believe, a typo of Amos' long ago.
Yesterday I cracked myself up. I'm webmastering our parish website-- good thing I proofrede, because about that raffle-- I had typed "Sinners need not be present"! (Winners)
And in a PM today, "fifference."
What are some of yours, or some you've seen and gotten a laugh out of? Not the timeworn bulletin bloopers, please-- fresh stuff from your life.
