The Brannock Device is such an old product

The Brannock Device is such an old product, so I wanted him to be like an old man who's got this big mustache and maybe he's a little grumpy," says Tripodi. "My original inspiration was Mr. Potato Head -- you can see it in his shoes -- and the overall design is based on a Goomba from Super Mario Bros, because I'm a big video game guy."

It was decided that Chuck would appear on the Chiefs' -- er, the Devices' -- one-day caps. That was simple enough: The logo was sent to MLB The Show 18 Stubs the team's headwear supplier, New Era, which slapped Chuck on the crown of a black cap. Voila! (Unfortunately, budget constraints did not allow for a live, costumed version of Chuck to be part of the promotion.)
