- This article is about the character. For the guest star, see Teller.
Teller is an American comedian, illusionist and writer. He is best known for his double-act with his fellow Penn Jillette.
He and Penn Jillette once had a show in Springfield. However, in the middle of it, Homer appeared on stage. To get him out, Teller mistakenly talked and then became scared because Penn will beat him. Penn started threatening that he will kill Homer and chased him on stage. Teller then said that Penn will certainly do it, as he isn't the first Teller.
Along with David Copperfield, Penn Jillette and Ricky Jay, he switched the trick milk can with a regular milk can to kill Cregg Demon, because he stole all their best tricks. Penn Jillette tried to explain their intention, but was silenced by Teller, because Penn talks on stage and Teller talks offstage, as the curse of the witch, put on them, said. When Lisa was about to save Demon, the four tried to stop her. Homer ran to save Lisa, but was captured in the cage by the magicians. Suddenly, The Great Raymondo appeared to rescue Lisa, much to Jay's surprise. Before attacking Raymondo, Teller prepared a magic light. Raymondo said that he's just an old man who couldn't fight them all, but he then cut the line keeping the scaffolding above the magicians which fell down on them. Penn's ponytail then burned what meant that the witch's curse was broken. However, Teller revealed to him that there never was a curse.
