Last night on Late Night, Jimmy Fallon followed Jay Leno's NBC diss with a much tamer joke of his own. "The rumors are true. NBC is turning the Tonight Show into a diving competition." After all, the Tuesday night debut of ABC's Splash, its D-list celebrity diving competition, ranked No. 1 in unscripted launches for the network since 2011. But those NBC rumors weren't the only thing that got Leno hot and bothered: Vanessa Hudgens booty-popped, just as she had done on Madonna's dance floor. Also, Eva Mendes tried on a dog shock collar; and Elle Fanning is in love with Eva's boyfriend, Ryan Gosling. She even has his coloring book, and she's very meticulous about it. No coloring outside the lines of those pecs. Watch our compilation to see what you missed.
