Yesterday I got my captain to do the bingo game PA. After he makes the PA he tells the passengers we're gonna play a game of bingo, and if they didn't get their bingo card just hit your flight attendant call button. Then he called off bingo numbers for about 5 minutes, we kept hearing ding's in the back about every 5 seconds or so. My stomach hurt I was laughing so hard. The flight attendant called up later and said people were actually getting mad because they didn't have their bingo cards!
