I was in a CRJ exit row a few days ago (CVG-CLT), as was one other gentleman across the aisle.
The FA was doing her routine start-of-trip safety announcement and rattled off the usual, "...if you are sitting in an exit row, you must be 18 or older." Then she paused, looked back at the two of us, and said, "...and I've checked the two guys out on this flight and they haven't seen 18 in a good long time!"
Good for a laugh!
