A Game of Bingo

I remember when I was a kid, my dad used to call bingo at the day care centre -- he nearly got thrown out by the matron a time or two for being a bit on the rude side, but the old ladies loved it.  ("Legs eleven, stairway to heaven" was a fave). 

The randomness of the balls, formed into a pattern by the cards, is actually a really great metaphor for life and I'm impressed with the way you've handled it.  It may be possible to tighten up some of the lines, get rid of a couple of prepositions and such, but it's an enjoyable poem.
