TV-Jay LenoJay Leno may still be smarting from that time Jimmy Kimmel slayed him during the Jay/Conan "Tonight Show" feud, since he's now dissing Kimmel's "mean-based" humor as the source of his not-quite-"Tonight" ratings. It's time for a late-night catfight!

Jimmy, a huge David Letterman fan, was probably already anti-Jay after the first "Tonight Show" feud between Jay and Dave, when they fought for Carson's chair. When Jay ended up in a late night battle with Conan O'Brien, Jimmy appeared to back Team Coco. Jimmy broke out his not-so-flattering Jay impression on "Jimmy Kimmel Live," then pretty much destroyed Jay -- to his face -- as Jay's own guest on "The Jay Leno Show." Here's how that went:


Jimmy Kimmel DESTROYS Jay Leno as a guest on...by Giagantor

Fast forward to 2015 and Jay Leno is returning to TV with "Jay Leno's Garage" on CNBC. TV Insider talked to Jay about his stand-up, and of course asked if he ever watched any of the new late-night shows, now starring Seth Meyers, Jimmy Fallon, Stephen Colbert, Conan and Kimmel. Here's Jay's response, complete with serious Kimmel shade:

I like Seth, I like Jimmy. I think Colbert will be really good. He's really clever. I don't know him well. The right likes to paint him as a tool of the left, but the man teaches Sunday School. He's a pretty conservative guy from what I can see. But he's a truly nice guy and decent human being. The most element you can have in doing a late night show is kindness. Because the show makes you arrogant. I think that's Jimmy Kimmel's problem. I think he's a talented guy, I think he's funny. But he has a mean streak, and it comes across. He does this thing where he takes Halloween candy from kids and the kids cry. What am I missing here? It is funny I guess, but it's mean-based. I think that's why he's not higher in the ratings."

Oof. That's almost worthy of its own "Mean Tweet" segment on Kimmel. Jimmy has a sharp sense of humor, and he's known for his pranks, but he definitely has a heart -- as shown in his defense of Cecil and attack on sport hunting. He also just officiated Jennifer Aniston's wedding.

"Jimmy Kimmel Live" has actually been on repeats for the past two weeks, so Jimmy had no chance to make a quip about Jay's latest diss. We'll have to see if he addresses it or just lets it stand. It's OK to have different styles of humor, so maybe nothing more needs to be said. But for the record, at least from here, those Halloween candy pranks are hilarious.
