text: If you're not superstitious, statistics is your friend.  People yelling "bingo!" all the time?  Ha!  There are people who have won the lottery twice!  Assuming there isn't any psychology also involved, the fact is that the human population is enormous and you're bound to get large subsets just through chance.  If one in 100 people is noticeably "lucky" and one in 100 are noticeably "unlucky" (just by chance), by golly, that's still 70 million people out there who are either lucky or unlucky!  That's a very rough argument, but there are two things you can do.  Either play bingo with these people for a long time-- you will discover that you win just about as often as they do-- or don't play bingo because it's a waste of money.  Seriously, though, just have fun!
