So I've Entered Him Into a Remedial Program for Catholic Adults

I take words pretty seriously. 
They're powerful, so I try to know a lot in case I need to look smart (which happens to be all the time--I keep very critical company).
In 2007, during an episode of The Office, they used the phrase "Pro-Am" and I laughed out loud. "HA.  That's hilarious. Pro-Am. No one even knows what that means!"
Matt seized on this opportunity, this rare and precious gift of my making a word-based mistake: "It means Professionals and Amateurs compete together."
So tonight, he's listening to some Christian light rock (Obviously. It's our pre-bar warm-up on Thursdays) and hears, "We'll beat our swords into plowshares...." He quietly muses, "What does that even mean?"
EXCUSE ME, EVERYONE. STEP ASIDE. I WILL HANDLE THIS.
"It means making your weapons into tools for farming that will benefit the whole."
"Ok, Pro-Am."
