Floyd Mayweather Jr. -- Strip Club Monsoon After T.I. Fight [VIDEO]

Floyd Mayweather Jr. practices what he preaches ... hours after getting into a fight with T.I. and telling him to "control your bitch," the champ went to a strip club to show how exactly how HE exercises ultimate control.

Floyd showed up at Larry Flynt's Hustler Club in Vegas at around 3 AM ... this after getting into a now-epic fight with T.I. at a nearby Fatburger.

We're told Floyd showed up with "bricks of money" -- making it rain to the point where one stripper was seen carting her cash away in a pillowcase.

2 Chainz, Flo Rida and Benzino cheered on as Floyd did what he does.
