George Eamonn Sunday (Ardal O'Hanlon) is a mild-mannered Irish health store shopkeeper, who is the first alter ego of "Thermoman". He inherited his title from his father Seamus Sunday, the original Thermoman, who is retired. George owns a health food store, but tries to avoid attracting customers in order to avoid attention. He often appears to be an idiot because of his unfamiliarity with Earth culture, and has a tendency to take things literally, such as allowing himself to get hit by a bus to cash in a life insurance policy without realising that he had to die. In the sixth series, he loses his body in a poker game, forcing him to assume a new alter ego, "George Monday". George's late mother was Ulrich Sunday.
