“Everything Is Awesome,” a.k.a. this year’s answer to 2014’s “Happy,” is going to be in your head Monday morning.

It’s yet another thing you’ll have in common with Oprah Winfrey.

Tegan and Sara and The Lonely Island took the stage at Sunday’s Academy Awards to perform the contagious The Lego Movie sing-along, which is nominated for Best Original Song. Naturally, awesome-ness ensued.

In keeping with the theme, Lego versions of the Oscar statue were handed out in the audience.

‘You get a Lego statue! You get a Lego statue! Everybody gets a Lego statue!’

Except Batman (Will Arnett), who also got in on the performance fun.

Basically, your childhood crashed the Oscars
