Jay Leno (who either will or will not be replaced by Jimmy Fallon next year) wrapped up a week of public bickering with ratings-challenged NBC by accusing the network of betrayal, in joke form. After relaying the story of a Canadian man who recently had doctors remove a knife that had been in his back for three years, Leno zinged, “Imagine that. The guy had a knife in his back for three years. He must have worked at NBC too.” And then he decided to do a poop boat reference: “Have you heard about this alleged feud that I’m having with NBC?” he asked. “I think it’s going to be okay. I had dinner last night with a bunch of executives [and] to make it up me, what they did, they are sending my wife and I on an all-expenses-paid Carnival cruise.” Elegant.
