No matter how you perform it, Meghan Trainor's "All About That Bass" is super catchy.
The 20-year-old singer/songwriter showed up on Thursday's Tonight Show to perform a special rendition of her hit alongside host Jimmy Fallon and The Roots using only classroom instruments.
This isn't the first time we've seen The Roots using plastic clapping hands. Fallon and the Tonight Show gang has performed a lot of catchy tunes this way, including Idina Menzel's "Let It Go," Robin Thicke's "Blurred Lines" and Mariah Carey's "All I Want For Christmas Is You."
What do you think of this version of "All About That Bass"? Play music critic in the comments and tweet #ETnow.
It seems nearly every day Fallon has another video going viral. ET uncovers his secret to success:
