Letterman admits he misses the latenight wars; calls Leno a "complete boob"

Dr. Phil McGraw made a passing mention on Monday night's "Late Show with David Letterman" about the recent late night wars -- and Dave took the opportunity to resume tweaking archnemesis Jay Leno.

"I loved it, I thought it was very exciting. It was great fun," Letterman said of the NBC "Tonight Show" debacle -- before launching into his patented Leno impersonation ("Yeah, yeah, we both got screwed!").

"I said, wait a minute Jay, you both got screwed -- but you're the only one who ended up with a show," Letterman said. "How did you get screwed?"

McGraw then defended Leno, arguing that The Chin had been given a "bum rap."

"He got everything he deserved," Letterman replied.

Letterman still appears giddy when referencing the Conan/Leno mess -- and admitted to McGraw that "I couldn't get enough of it, and I wish it was still going on."

Replied McGraw: "I'm sorry I asked."

"I've known Jay since 1975," Letterman explained. "Everybody loved Jay because he's so funny, you can't not like him. But then there's also this other side of him, and I think he'd own up to it, that he's just a complete boob. He can't help himself. ... We were all able to say, 'Oh here's the Jay we remember."
