Brian Williams Raps About 'Gin and Juice' on 'The Tonight Show' (Video)
Jimmy Fallon invited one of his favorite guests back to The Tonight Show on Monday -- NBC Nightly News anchor Brian Williams.
True to form, Williams was the subject of another "Rapper's Delight" video, which featured the familiar formula of clips of him reporting the news spliced together to make it seem like he's rapping.
The latest creation, titled "Gin and Juice," featured classic lines from Snoop Dogg's hit, such as, "I've got a pocket full of rubbers and my homeboys do too.... Sipping on gin and juice, with my mind on my money and my money on my mind."
Over on ABC, Jimmy Kimmel pitched a superfan against her idol, Katy Perry, in a game of "Who Knows Katy?" The singer lost out to her devoted follower, who won a pillow for answering questions like "Why was Katy thrown out of school?"
Billy Bob Thornton was also on Jimmy Kimmel Live!, talking about his family's Easter egg hunt -- "I'm getting old and don't see too well, so for me they hide traffic cones" -- his strangest auditions (he once had to pretend to shoot someone with a stapler), and his dark new role on Fargo.
On CBS, David Letterman asked Courteney Cox something she's heard a million times -- if there's going to be a Friends reunion.
"You're sick of that question, aren't you?" he said.
"It's not going to happen," said the actress firmly. "There are six friends, and I have been trying to put together a cast dinner for 10 years -- it ain't going to happen. You can get the girls, and maybe Matthew Perry will come; Matt LeBlanc canceled right at the last minute," she explained.
On the Late Late Show, Craig Ferguson chatted with George Lopez about his recent health kick. "It was time to turn over a new leaf," confessed the comedian. "I had an incident in a casino -- anybody seen it? -- I wanted to get up with less strain if I was going to fall down drunk," he joked, referring to a recent night when he was arrested after passing out in a Canadian casino.
Lifelong Red Sox fan Seth Meyers began his show with a dedication to the people of Boston and being thankful that the marathon was run safely this year, while noting that his beloved baseball team had lost their annual game after the race.
He went on to welcome John McCain, and the 2008 Republican presidential nominee joked that he had only asked Sarah Palin to be his running mate because she looked like a certain Saturday Night Live cast member. "It made Tina Fey famous forever -- that's why I selected her," he said.
