Fernhill Mint is a company that produces expensive mugs which make people feel more important. This company was mentioned in Life in the Faust Lane, in which Earl Sinclair trades his soul for one Fernhill Mint mug, Cap 'n Willie. B.P. Richfield owns 13 Fernhill mugs.

Fernhill mugs are apparently so valuable that owners need special security systems in order to protect them from being stolen. As a spokesman on the Dino-Shopping Network says, "You may not be able to afford one, but can you really afford not to have one?"
