Her cover of the SpongeBob SquarePants theme song has to be seen to be believed.

Jimmy Fallon and his wife Nancy each told their version of the milestone moment — except their memories didn't fully match up.

Fallon and the Happy's Place star performed an impromptu duet...mere inches from an audience member's face.

Jimmy Fallon dusted off his Joe Biden impression for a faux phone call with "Barack Obama" following the June 27 presidential debate.

"You know what I respect about you? You knew when to give up making movies entirely," Reynolds told Fallon.

Murray, Naomi Osaka, and more tennis stars injected some silliness into their U.S. Open sound bites, with help from The Tonight Show.

In 2015, Black and the Tonight Show Host hilariously recreated the music video of the bands '90s hit.

Eddie Murphy said Charlie Murphy's Chappelle's Show story was "accurate" — except for a couple details he shared with Jimmy Fallon. 

Wiig, who voices Lucy Wilde, also shared the one sound effect she's "so bad" at.

The Tonight Show Host's 2011 impression is featured in the new documentary, Butterfly in the Sky: The Story of Reading Rainbow.
