Mary-Kate And Ashley Pick On Elizabeth Olsen In This Throwback Clip

    Mary-Kate and Ashley tell their younger sister to "B-U-T-T out".

    The talented and insanely gorgeous Elizabeth Olsen plays Wanda Maximoff, aka Scarlet Witch, in The Avengers: Age of Ultron.

    She is also the sister of twins Mary-Kate and Ashley Olsen.

    Who used to look more like this...

    After the twins rose to fame in Full House, they embarked on a ton of projects, including a series of sassy music videos with titles like "Brother for Sale" and "I Am the Cute One".

    As you may recall (don't lie, you had all of these on VHS), the videos were part of The Adventures of Mary-Kate & Ashley, a series of musical mystery videos.

    In one video called "B-U-T-T Out" they sing (and rap!) to their sister Lizzie, telling her she needs to back off because she can't join them.

    All she wants is to be part of their adventure, but the twins wag their fingers and tell her to go away.

    The lyrics of this track include:

    🎵 "Now back off and say goodbye.

    We'd rather be picked up by a twister,

    Than tagged along after by a sister.

    We'd rather eat French-fried garden snails,

    We'd rather lose all our fingernails,

    Or bathe in a pool of slime!

    Hasta la vista, baby sista!

    Maybe some other time." 🎵

    Look at that attitude!

    The highlight has to be when they tell poor, miserable Elizabeth: "Eat your ziti!"

    This zinger is followed by the closing lyrics, which go:

    🎵 "Phone home, ET, go home ET, B-U-T-T out!

    Take a hint, take a hike, B-U-T-T out!

    Ya betta, ya betta, ya betta, ya betta, B-U-T-T out!" 🎵

    Luckily for Lizzie, she didn't let this song get to her – look at her now!
