Rigby's is the name of a store where Kenan works and, technically, is created on set.  The store is owned by Chris Potter and Kenan Rockmore is part time there too. Chris doesn't seem to know that Kenan hardly does actual work whilist in the shop with his friend, Kel, who constantly drinks orange soda and does not pay for it. Kel always hang's out in the store, besides Kenan's house.
