Dave Chappelle: I APOLOGIZE to the Seminole Indians

24 hours after BOMBING during a stand-up performance at an Indian casino in Florida, Dave Chappelle has issued an apology to the tribe ... claiming it's not the first time he's flopped on stage.

As we previously reported, Chappelle was performing at the Seminole Hard Rock Hotel and Casino in Florida on Friday night ... when things got so bad, he began texting in the middle of his show.

But the next day, he apologized for what he called a "wild night" -- and gave a "big shout out to the Seminoles."

Chappelle says he had a similar experience at the MTV VMAs back in 2004 -- and the way he tells the story ... pretty damn hilarious.
