I once was on a puddle jumper with maybe six rows in an exit row. The captain came on board last (no flight attendants on a flight this small) and stopped by my seat to go over the emergency row particulars, like how to open the door in case of an emergency, etc.
Once he finished, he asked me "You got it?"
"Sure!" I said.
"Good. Now remember... no practicing on this while we're in flight!"
