Here's my keno system.
I'm in the club and pull out a lobster to play keno.
I then remember that $20 can buy me 8 schooners and I say to myself "what is more enjoyable; 8 delicious cold schooners of Black Old or cheering for number 69 like a dill for 25 minutes?"
As the last coldie slides down my gullet I am sure I have made the right choice.
