Bogdanovic method

Named after the famous professor, Dr. Bogdanovic, who made millions off of this method; the Bogdanovic method is used to guarantee you to walk away with casino earnings after playing hours at the roulette table. The method is implemented as follows:
1. Start with a lot of money/chips.
2. Bet low (like $1) on one color (black or red).
3. Continue to bet $1 on that same color every time you win.
4. Double your bet on that color every time you lose.
5. Walk away with money gained in your pocket at the end of the night.

Dude 1: Ah...Bogdanovic method.
