New York ? Jimmy Fallon is a kid in a candy store.

He’s chosen to meet for this interview in a Rockefeller Center chocolate shop downstairs from the “Saturday Night Live” studio, where he’s made his name as the irreverent yin to Tina Fey’s prim yang on the “Weekend Update” anchor desk. He comes here a lot, he says, because it’s a quiet place to sit and read scripts, and because the hot chocolate is “absolutely perfect.”

Comedian Jimmy Fallon will host this year's MTV Video Music Awards show, has put out a comedy album and just finished shooting a Woody Allen movie. The Saturday

He makes sure you have the hot chocolate, too. “I just can’t wait ’til you try this you’re really gonna love it,” he gushes. “It’s so perfect. It’s like pudding, right?” (He’s right it’s yummy.)

The 27-year-old has that same boyish enthusiasm about everything he’s doing these days and he is doing everything.

You can’t turn on MTV without seeing Fallon singing and dancing in commercials for the MTV Video Music Awards, which he hosts Thursday night.

You also can’t miss Fallon’s own video for “Idiot Boyfriend,” the first song off his debut comedy album, “The Bathroom Wall,” which just happens to hit stores two days before the VMAs. In it, Fallon, a product of ’80s pop culture, spoofs videos ranging from Prince’s “When Doves Cry” to Bobby Brown’s “Every Little Step.”

MTV and MTV2 president Van Toffler said the comedian was a natural choice to host the VMAs after he co-hosted the MTV Movie Awards last year with Kirsten Dunst.

“He knows everything about contemporary pop culture, and in particular he does blow-away impressions of contemporary artists,” Toffler said.

Fallon’s goofy humor is vastly different from the in-your-face style of last year’s host, comedian Jamie Foxx, who saw some of his harsher jokes land with a thud. But Toffler said that’s not why MTV chose Fallon.

“Clearly we want this to be the last big bash of the summer, especially before the country takes on a very somber tone around the anniversary of Sept. 11, and Jimmy can be both insightful and funny and light and sincere,” he said.

Fallon also just finished shooting the Woody Allen movie “Anything Else,” with Jason Biggs and Christina Ricci, which is scheduled to come out next year.
