'Scrambled Eggs': Paul McCartney & Jimmy Fallon Sing Alternate Version Of 'Yesterday' (VIDEO)

How many comedians can say they've sung with a Beatle? On Thursday night's "Late Night," Jimmy Fallon was given the honor of singing a tune with Paul McCartney, who was the night's featured guest.

But they didn't just sing any old Beatles song. Fallon got to sing the original placeholder lyrics to "Yesterday," which make the song have less to do with love being an easy game to play and more to do with food commonly found at a diner. "Scrambled eggs/Oh my baby how I love your legs," is how it starts, and it just gets sillier from there.

We can't wait to see if McCartney has any more funny stuff up his sleeve for when he appears on "Saturday Night Live" this weekend.
