From the color of money. Line spoken by the character "Grady Seasons". In real life Keith McCready, a true money player. Reading the script, he said no real pool player would say the things written for him. So, after being asked what a pool player would say, Keith came up with this..
Another funny aside. Keith did lead a pool hustler lifestyle, never really had a home address. Finally, after a "good woman" semi rehabilitated him, the screen actors guild was able to find him. It seems he had a small fortune in residual payments coming. It came at the right time.
