Have you ever wondered what your dog is thinking? Chances are it has something to do with food, squirrels or fire hydrants, but if you want to know for sure what Spot might be plotting, Warehouse 13 could hold your answer. VIP Fan Auctions is offering the pair of fez artifacts that once belonged to entertainers Mr. Mental and his chimp, Coco. An inventor with a background in neurology, Mr. Mental designed the hats to transmit brainwaves between human and animal, allowing the human to read the mind of the animal. Just beware – the hats must be removed simultaneously, otherwise a debilitating shock is delivered to whomever is still wearing the other fez. The fezes (pictured above) were first featured in the episode “Past Imperfect” and were created by the Warehouse 13 props department.
