Hank is a little animatronic comedian built by Ford which runs a comedy act at the State Fair in Texas. I guess you could call him a robot, but I'm pretty sure (SPOILER ALERT: don't read if you still believe the tooth fairy is an actual fairy and not a goblin that touches you while you're sleeping) Hank just stands there waving his arms around while somebody does all his speaking for him from a hidden location. There, I ruined it. The gig is up Hank, you'll never work in this town again.
UPDATE: Now he's a Walmart greeter. I hit him with my cart!
Thanks to Ken, who promised to run into him a few times with one of those complimentary Hoverounds first chance he gets.
