The only undefeated pro wrestling champ ... when it comes to drinking ... is Andre the Giant -- so says another WWE legend -- Jerry "The King" Lawler.
Before he was announcing, Lawler used to wrestle and hang with the French giant -- and tells us A.T.G. could drink more than anyone he knows ... or YOU know, for that matter.
As Jerry walked out of LAX ... he also revealed the exact amount of beer it took to get 7'4", 500 lb. Andre drunk, and let's just say ... George Lopez would be proud.
Definitely ... Eighth Wonder of the World.
