Jimmy Kimmel makes a dig at Jay Leno while bidding adieu toConan

It’s like 2010 all over again.

“I also want to congratulateConan O’Brienon 28 years of very funny late-night television.

Conan wrapped up his show on TBS tonight,” Kimmel told his audience.

“Anyway, here’s to Conan andAndy Richterand everybody involved with that show,” he continued.

“We look forward to whatever you have planned next at HBO Max.

And I also want to say, congratulations to Jay Leno on his new time slot at TBS.”

Kimmel’s joke was a more-than-decade-old reference to the much-documented late-night dust-up between O’Brien, Leno, and NBC.

For example, one of Leno’s questions was about the best prank he ever pulled.

The late-night host also helmed an entire episode ofJimmy Kimmel Livewhile dressed as and parodying Jay Leno.

“Hello, hello, I’m Jay Leno.

“You know what ABC stands for?

Always bump Conan.”

Leno later went on to tell Oprah Winfreyhe felt “sucker-punched"when the 10@10 segment happened.
