David Spade once got caught paying $9,000 for Adam Sandler's dinner

David Spade once bravely volunteered to pay for Adam Sandler's $9,000 dinner which caused the most hilarious and unexpected interaction ever.

It's not unusual for pals to pick up the bill for their friend after going out for food and drinks, but most people probably haven't had to part with thousands of dollars without realising it.

The Grown Ups star and writer sat down with talk show host Jimmy Fallon on The Tonight Show where he revealed a hilarious story about his former Saturday Night Live co-star.

Both Spade, 59, and Sandler, 57, are two of the biggest names in comedy and they’ve been in massive films over the years, which means they both probably have a few extra coins to splurge on dinner.

But Spade was totally unprepared after paying for Sandler's bill, unbeknownst of what was to come and how bank would react.

“Adam [Sandler] he always buys me dinner, you know, he’s just a nice guy and his wallets about 10 feet tall and then he has to bend it closed,” he told Fallon.

“But, we were all out - or I was out at dinner at some fancy restaurant and then they go, ‘Mr. Sandler’s here’ and I go, 'Ooh!' I play it down. I go, ‘Who cares?’ you know," he explained.

"But then he’s got this whole back room with 15 people and they’re having some big birthday party or something. So, I go in there and I do a few thirsty bits to get attention. And then I leave and come back.”

As the audience laugh, Spade continued: “And then, when I leave, I go, ‘Hey, put this on, you know, my Discover card’ or whatever, so I charge theirs. The guy goes, ‘Sir, his whole thing?’ I go, ‘Yeah. I’m on TV sometimes. What are you worried about?’ So, he goes, ‘Sure’.”

The Just Shoot Me! star found out exactly how much money he spent on the You Are So Not Invited to My Bat Mitzvah actor the very next day.

Unfortunately for Spade, he woke up to a call from Identity Guard who relayed the terrifying message: “Someone stole your card.”

Spade was surprised by the news but then learned it was all a huge misunderstanding, leading to what must have been a massive and funny relief.

“'There was some $9,000 dinner last night’ I go, ‘Oh my God’. I go, ‘That was me’. They were like, 'It couldn’t have been, you’re not that generous'. I go, 'No, I was buzzed'.”

The pair have remained friends ever since appeared on SNL together in the '90s and they starred together in the hit movies Grown Ups and Grown Ups 2.

Let's hope Sandler returns the favor one day!
