So, who's the victim now, hmmm?
Suffice it to say, he didn't exactly rise to the challenge.
While Leno's full sit-down with Her Oprahness won't air until tomorrow, the good people at Harpo have unleashed an anticipation-building clip of the yakkers' conversation.
"I haven't talked to him since all this," Leno says of O'Brien.
When pressed by Oprah as to whether he ever wanted to reach out to to his one-time successor, Leno admitted it had crossed his mind, though it didn't exactly sound like it was at the top of his to-do list.
"It didn't seem appropriate," he says. "I don't know, I think, let things cool down and maybe we'll talk, you know?"
Still, that's enough about What's-His-Name. Let's get back to the real victim in all this.
"No, they were jokes," Leno answered, not quite convincingly. "And that's OK."
"It's what we do, you know. You can't...It's like being a fighter and saying, 'When you got punched in the head, did it hurt?' Well, yeah, but you're a fighter, that's what you do."
It's safe to say that's the sort of legacy not everyone hopes to leave in their wake. We're calling this round for Team CoCo.
Team CoCo's got the better numbers, but Team Leno has some seriously strong backers. Just ask Obama.
