These getlemen were playing high-stakes poker in a casino when suddenly a blond comes in and heads to the coke machine. She puts in her money and gets a drink. Then she lets out a little cheer which upsets the poker players significantly.
Oddly enough, instead of taking her drink and moving on she puts in more money, gets another drink, and lets out another cheer. Then she repeats it a third and fourth time.

Her reply - “DUH! Winning!!!”
