Jerry "Pachyderm" Persheck (also known as "The Derm") is referenced by all four major characters in the episode "The Stand In". One evening Pachyderm exclaimed that he was going to approach a woman; however, before approaching her he grabbed two pieces of pizza that were much too hot with his bare hands. Pachyderm, determined to approach the woman, held the two burning pieces of pizza in his hands until he resorted to juggling them which ultimately resulted in him throwing the pizza in the air. According to Elaine, the whole place "went crazy" when one piece landed on Pachyderm's face and the other landed on the woman's face. At the end of the episode George's girlfriend leaves him for Pachyderm who has apparently resorted to repeating the pizza event as a way to pick up women.
