"I’ve often wondered why, in Albert Brooks’ movie
Lost in America, the wife insists on continually playing the number 22 at the
roulette table, even though she eventually loses the nest egg doing
so.Why 22?Was it meant somehow to refer
to Catch 22, or did Brooks simply want a funny number to offset the grimness of
losing one’s fortune?"
