Jimmy Fallon took his infamous lip syncing battle to VidCon this year where hundreds of YouTubers gathered for conventions and fan meetups in California.

This battle showcased the talents of a wide array of YouTube favorites, including Mamrie Hart of “You Deserve A Drink,” Britain’s Mazzi Maz, Sam Pepper, Fred, Oli White and Alexa Losey.

The song lineup was pumpin’, with hits like Iggy Azalea’s “Fancy,” Katy Perry’s “Teenage Dream,” Nicki Minaj’s “Superbass” and DJ Snake and Lil Jon’s “Turn Down For What.”

I think Mamrie did “Fancy” some justice. That curtsey at the “LA to Tokyo” lyric point was priceless.

Surprisingly, the YouTuber’s did well with “Superbass,” which, if you’ve heard the song, features some fast paced rap verses. Impressive.

Things got awkward when the song switched to “Teenage Dream,” and the YouTubers began serenading a cardboard cutout of Jimmy Fallon. I wonder whose idea that was…

Attempting to lip sync to “Turn Down for What” turned into a dance battle. A very interesting dance battle, I might add.
