Tantalus

A gluttonous king who tried to offer his son Pelops to the gods. He chopped Pelops into pieces and served him to the gods as a stew, with only Demeter tasting it. The gods were horrified, and they revived Pelops, giving him an ivory shoulder to replace the one Demeter ate. Tantalus was punished in the Underworld by being forced to stand in a pool of water up to his knees and underneath a cluster of apples. The apples would forever be out of his reach, and if he tried to drink from the pool, the water would recede.
