The cast of Avengers: Infinity War visited Jimmy Fallon’s Tonight Show Wednesday and performed a very entertaining parody version of The Brady Bunch theme song, complete with blue box grid and all.

Iron Man‘s Robert Downey Jr. kicks off “The Marvel Bunch” with “the story of a playboy genius, who was gearing up to form some sort of crew.” He’s then joined by Scarlett Johannson (Black Widow), Chris Pratt (Star Lord), Chris Evans (Captain America), Chris Hemsworth (Thor), Benedict Cumberbatch (Dr. Strange), Chadwick Boseman (Black Panther) and Anthony Mackie (Falcon)

See lyrics in full below and video above.

Here’s the story

Of a playboy genius

Who was gearin’ up to form some sort of crew

With a former Russian spy

A god of thunder

One fought in World War II

Here’s the story of a handsome Star Lord

Like the greatest to every walk the earth — by far

And a Falcon

And a magic doctor

Wakanda forever!

‘ Til then one day all the heroes were assembled

To fight a villain who packed much more than a punch

And this group was labeled the Avengers

That’s the way we all became the Marvel Bunch

The Marvel Bunch

The Marvel Bunch

That’s the way we became the Marvel Bunch!
