As you might have guessed — especially if you already hit play on the video above — Oswalt is lending his voice to Bart’s guilt, which manifests itself after he lies about throwing away Lisa’s favorite hat. Oswalt first guest-starred in Season 24’s “The Day the Earth Stood Cool,” voicing a pint-sized hipster named T-Rex.
In addition to offering a first look at Oswalt’s (surprisingly violent) guest spot, TVLine’s exclusive behind-the-scenes video also showcases the actor’s
nerdy impressive wealth of Simpsons knowledge.
