Adam Sandler was lunching with buddies at an LA diner when an assistant rushed in with the first reviews of his smash-hit “Punch-Drunk Love” — and the star went berserk! “These are the first good reviews I’ve ever gotten,” Adam crowed.

Then Adam really shocked ’em, shouting, “Lunch is on me!” And he picked up the tab for about 30 diner diners!
