The 2004 cult movie favorite ‘Napoleon Dynamite’ returns as an animated comedy on Fox next week, with original Napoleon Jon Heder voicing the title role.

To promote the new show, Heder showed up on ‘Late Night With Jimmy Fallon’ Monday in his famous Napoleon Dynamite outfit, and proved that he still has all his most famous character’s incredulous “jeez” and “whatevers” down pat.

In the clip below, Napoleon teaches Fallon how to hunt a woolly mammoth, and the pair engage in a contest to see who can slay the prehistoric beast first. Don’t worry, no real woolly mammoths were hurt in the filming. Duh!
