He’s the US actor who played one of the most loveable misanthropes in television history.

And Seinfeld star Jason Alexander has revealed his most favourite moment from his character George Costanza from the iconic sit-com.

Jason, 65, was appearing on The Project on Thursday to promote his new collaboration with Uber Eats, when the subject quickly turned to his most recognisable role.

Host Waleed Aly asked Jason to divulge his favourite Costanza moment and it didn’t take long for the actor to think of his answer.

‘George got hoisted on his own petard so many times, and had to dig himself out of a hole, or not dig himself out of a hole,’ Jason said.

He then revealed his most memorable Costanza moment came in the season three episode titled the Red Dot, that sees George engage in a romantic dalliance with his office’s cleaning woman.

‘The one that I remember so clearly, because I thought it was so brilliant, was in an episode where George was working at the publishing company and he was having sexual relationships in his office with the cleaning woman and he got caught,’ Jason explained.

‘If you’re writing that scene and you’re going: “okay I’ve got this guy George Costanza, what happens next? Whatever you would imagine it wouldn’t be what they came up with.’

Jason then repeated George’s immortal rebuttal of: ‘Is that wrong’?

He went on to reveal that the way that creators Jerry Seinfeld and Larry David created George’s response to the sticky situation gave the actor incredible insight into George’s mind.

‘That is the most brilliant try to save your own behind that I could have ever imagined,’ he said.

‘The one that i remember so clearly, because I thought it was so brilliant, was in an episode where George was working at the publishing company and he was having sexual relationships in his office with the cleaning woman and he got caught,’ Jason explained

‘When I first saw that script and I saw that was the approach they found, that was a big insight into who that character was for me

‘It was really very helpful for me in understanding how the mind of George Costanza works.’

Waleed admitted that he had almost forgot about the scene, which originally aired back in 1991, until Jason began retelling the story.

After repeating George’s iconic rebuttal of ‘is that wrong’, Jason added: ”That is the most brilliant try to save your own behind that I could have ever imagined’

Replying, Jason said that was a testament to the show’s creators.

‘Jerry and Larry were writing a kind of comedy that was very new,’ he said.

‘It had a different shape, it had a different sound, it had a different music. It was focused on different kinds of stories and different kinds of characters. Back then it was very risky and off the beaten path.’
