"Doctors in Canada were shocked after pulling a 3-inch knife blade from the back of a 32-year old man," Leno began. "The knife had been in there for three years! Imagine that, the guy had a knife in his back for three years. He must've worked at NBC too. I was stunned by that.""Have you heard about this alleged feud that I'm having with NBC?" he continued. "I think it's going to be OK. This is real: I had dinner last night with a bunch of NBC executives. To make it up to me, what they did, they are sending my wife and I on an all-expenses paid Carnival cruise. How about that? So it looks like it's going to be OK. Fantastic!"
