Reuben Grinder

The owner of the Edible Edibles sandwich shop (voiced by Nick Kroll), who was being robbed by Chuck in "Chuck Makes A Buck". Mr. Grinder employs Chuck thanks to WordGirl as the store's spokesperson/mascot due to his sandwich face, and he becomes popular. However, in a falling out at his store on sandwich making for the annual Fancy People's Annual Awards Dinner, Chuck quits and turns the floor at the ballroom into the bottom half of a sandwich in which Reginald states that "the upper crust [of the sandwich] is going to crush the upper crust [the fancy people]". His name comes from two forms of sandwiches: the Reuben and the Grinder, a toasted hero sandwich. He and Brent later went into business together selling Peanut butter bread and Jelly bread.
