Here's a recent verse:

Stop at Player Service
Ask them for a card,
Ask them for a card.
Ask them for a Blackjack Basic Strategy card.
It's free and on the level;
It's a basic strategy card.
Bound to lose,
Bound to lose.
But you won't lose as much as you would otherwise.

(This may be the first occurrence of the word 'otherwise' in a folk song.)
