Jimmy Kimmel’s July 19th show was to be all about his very own blackjack-playing Aunt Chippy. Until Matt Damon showed up.

While Kimmel was at the studio, Aunt Chippy was at the Cosmopolitan of Las Vegas to play some serious blackjack for Kimmel’s studio audience. His aunt won $100,000 when she played for Kimmel’s studio audience way back. Chippy was supposed to be the lone player on the table but when the camera panned out, there sat Matt Damon disguised as a mullet-sporting, Ray-Ban dude.

When Jimmy saw Damon sitting comfortably with Aunt Chippy on the blackjack table, Kimmel quipped that Damon was not supposed to be there. Aunt Chippy chirped that if she had known Damon would be there, she would have shaved her legs.

Damon explained to Kimmel that he was in Las Vegas for the world premiere of his latest Jason Bourne saga. He said that he thought of dropping by the casino to actually play blackjack with Aunt Chippy.

Jimmy Kimmel resigned to the fact that Damon was there to play cards. So the game began. The sad truth was that Aunt Chippy lost all her money on the first round.

Kimmel was fuming mad and blamed Damon for the loss. He said that they no longer have money because Damon showed up and now they are left with nothing.

However, all was not lost as Damon said “Hang on. Wait a minute. Jimmy, I was thinking, you know. I don’t know if you’ve ever seen $10,000, but I personally like your studio audience a lot, and I feel like some of them like me.” He whipped his hand and gave Aunt Chippy the extra cash.

The dealer dealt the cards. Aunt Chippy’s bet of $10,000 won $20,000. Everyone was happy as the bet was doubled. Chippy chose to role the money and won $40,000. Kimmel actually said that in spite of Damon, they were actually winning. On the third deal, all of the money won went down the drain. No worries though as Matt Damon produced another $10,000 for Aunt Chippy. This time though, Chippy lost. And that was that!
