During the homily the priest asked: "Does anyone know why we celebrate John the Baptist's birth on June 24th?"
Well, being a theology teacher, I raised my hand quite confidently. As I was one of the only ones, the priest called on me. I was about to impress the entire congregation with my knowledge. We celebrate the Annunciation on March 25th. Gabriel at that moment tells Mary that Elizabeth is 6 months pregnant with John. So I shout:
"June 24th is 6 months from March 24th"
The church began to murmur, no doubt horribly impressed.
Then my wife said in my ear: "That's THREE months."
It was then that I noticed that the murmurs were actually giggles, now accompanied by pointing.
To which I shouted back to the congregation:
"I can't do math!"
