Everything really will be awesome when Will Arnett takes the Lip Sync Battle stage for the show's return on Thursday. 

While many celebs opt for classic hip-hop hits (ahem, Arnett's competitor Alison Brie), the Arrested Development star went full kid zone for his take on the theme song from last year's The Lego Movie by Tegan and Sara featuring The Lonely Island

Channeling the ensemble's original epic performance during the Academy Awards, the 45-year-old funnyman—who voiced Batman in the Lego flick—sports a bright orange construction suit and hard hat while a team of similarly dressed backup dancers rock out behind him.

After busting out the robot, Arnett really hits his brick-shaped stride when the rap verse comes in. Even his BoJack Horseman co-star Brie, who delivers a stellar rendition of Salt-N-Pepa's "Shoop," looks thoroughly impressed with the performance. 

To see just how awesome Arnett is, watch Lip Sync Battle this Thursday at 10 p.m. on Spike TV.
