Comedian Jerry Seinfeld promoted the new season of Comedians in Cars Getting Coffee, but it sparked a little debate.

Seinfeld called out some shows that he claimed were “influenced” by his idea, including Carpool from British comedian, Robert Llewellyn.

In the new season trailer for Seinfeld’s Netflix series, he says, “These are all real shows! And we are proud that others have taken notice of our style and have been inspired by it,” he said. “The only comment we would like to make is: If you’re going to knock us off, get it right!”

This caught Llewellyn’s attention, who took to Twitter on Wednesday to say that his show, Carpool was first.

“This is only of any interest because of the original Carpool,” tweeted Llewellyn. “Started a full 3 years BEFORE Jerry and his pals copied it. LOL.” In his tweet were also links to his show and the account Netflix Is A Joke.

Carpool streamed online in 2009, and aired on TV in 2010-11 predating Comedians in Cars, which debuted in 2012.

Seinfeld tweeted, what seemed to be an apology, to the British comedian.

“Apology to Robert Llewelyn Car Pool. Had not heard of it,” said Seinfeld.

Llewellyn tweeted back with, “That’s very kind of you sir. I’ve moved on since the Carpool days but the series is still up on YouTube.”
