Check out this video of Michael Cera and the infamous Bluth Company stair car. Mitch Hurwitz, creator of the show, films young Cera demonstrating the stair component of the stair car and attempts to tie-in a promo for the "You're Gonna Get Some Walk-Ons" contest, which will award walk-on roles to six lucky fans. Cera doesn't appear to know anything about the contest, but perhaps he's in character. The contest ends Oct. 16. Visit the official website to enter.
