Charlie Sheen -- George Lopez Is an Amateur -- This Is How You Pass Out!!!

George Lopez is sorely mistaken if he thinks he can out-party the party king -- Charlie Sheen sent him a clear message on the set of "Anger Management" Tuesday ... no one passes out like the Warlock.

The clip's pretty funny -- Charlie and George shot it together ... mocking George's recent arrest at a casino for public drunkenness.

George paid Charlie a visit after scoring a major deal at FX for his new show "Saint George," the same exact deal Charlie got for "Anger Management" -- a guaranteed 10 episodes with a promise of 90 more if the ratings are good. It's a small gamble for a HUGE payoff.
