Paul Rudd battles Jimmy Fallon on ‘Tonight Show’ lip sync contest

Jimmy Fallon has learned a valuable lesson in Week Two of his “Tonight Show� run: Never ever challenge Paul Rudd to a lip sync contest unless you’re prepared to go all out.

On Tuesday night’s show, Rudd and Fallon had “Tonight’s� first such contest. The rules were simple: two songs were selected. Neither competitor knew what the other picked. And the winner was the person who lip synced the best.

As a guest on the show, Rudd had the honor of going first, and his selection was Tina Turner’s “You Better Be Good to Me.� Rudd gave an impressive showing, but Fallon would not be outdone.

The “Tonight� host countered with Foreigner’s “Jukebox Hero.� Fun, energetic, a typically Fallon-esque performance.

But not even Fallon could top Rudd’s final song, a blistering lip syncing of Queen’s “Don’t Stop Me Now.�

How awesome is it? So awesome that Fallon didn’t even bother to do his second song.

“I concede!� he yelled. “The winner right there!�
