Porque isso aconteceu no episódio 11 da 1ª temporada:
Phil starts changing his billboard messages from "Alive in Tucson" to "Moved to Tampa", but his ladder falls while he is working on his first sign, leaving him stranded. A new, handsome man (Boris Kodjoe) arrives and rescues Phil, driving him home. To everyone's surprise, the new man is also named Phil Miller. Confusion over having two Phils results in a competition that the original Phil loses. As a result, he is now to be known by his middle name, "Tandy".
