VIDEO: Will Ferrell Performs Handwashing Songs on THE LATE LATE SHOW

Will Ferrell performed a very passionate hand-washing medley on The Late Late Show's Homefest.

"I have been washing my hands obsessively as I'm sure all of you have, and they tell us we're supposed to spend at least 20 seconds washing carefully," Ferrell said. "A lot of you mark the time by singing 'Happy Birthday'. But you know, that's not the only song you have to sing."

Ferrell goes on to sing a bunch of alternatives, from Snoop Dogg to Sia.
