We finally have the proof that Tom Hanks really is that oversized kid he portrayed in the 1988 film "Big." All it took was a giant piano keyboard in the floor for the actor to dance on.

During an appearance on "The Jonathan Ross Show," Hanks steps up and shows he hasn't lost his ability to tickle the ivories with his toes. He even busts out the "Chopsticks" and is left tugging his pants back up a bit just like he had to do after the famous department store scene in "Big."

In the movie, Hanks plays the adult version of a boy named Josh, who wishes he could be big. Trapped in a grown man's body with the mind of a 12-year-old, Josh's youthful spirit rubs off on the adults around him. It all plays out famously in a piano scene where Hanks and actor Robert Loggia dance the song "Heart and Soul."

On the "Ross" show, the host asks Hanks, "You want to try something faster? Just show us what you can do." Hanks, 57, then jumps on the keyboard for a rapid-fire tap session that fails to keep up with the music. That's OK, and because we weren't smiling quite hard enough, out comes actress Sandra Bullock.



It just so happens the two have the most buzzed-about movies out right now, as Hanks stars in "Captain Phillips" and Bullock leads the box-office smash "Gravity."

"Now we can do 'Chopsticks,' but maybe not in your heels," Hanks says to Bullock. "Oh, I can do 'Chopsticks' in my heels," she replies confidently, as the camera zooms in on her footwear.

And with that, two of Hollywood's most lovable stars show why that's the case as they bounce atop a piano in the floor and remind us all what it's like to be young at heart.
