Character Information
Zack works at the Cheesecake Factory with Penny and designs the menus. He is very proud of inventing the word "Appiteasers﻿". Though usually a friendly, outgoing person, he is extremely dimwitted and displays even less understanding of sarcasm than Sheldon does. In The Lunar Excitation, he goes on a date with Penny, who, allegedly due to having dated Leonard, finds him insufferable for his stupidity and winds up having a drunken sexual encounter with Leonard the same night. In The Alien Parasite Hypothesis, he briefly meets Amy Farrah Fowler, who instantly feels sexually attracted to him. Though she later approaches him at a bar hoping for sex with him, his stupidity becomes too much of a turnoff for her to go through with it. When they shake hands, Amy whimpers, saying that "should hold [her] over" for a while. Penny gets back together with Zack again The Justice League Recombination, later admitting to Leonard that she only did so in order not to be alone on New Year's Eve. In this episode he attempts to befriend Leonard, Sheldon, Raj, and Howard. He dresses up like Superman for Stuart's New Year's party, helping them complete their Justic League theme. They apparently broke up again some time afterwards. Zack appeared in The Toast Derivation, having been invited to Sheldon and Leonard's apartment by Sheldon. This was his attempt to establish a new social group, along with Barry Kripke, Stuart, and (Sheldon hopes) LeVar Burton, after Sheldon becomes angry with his friends for eating at Raj's apartment. Zack impresses Stuart and Barry with his tale of a naked woman in a hot tub, and later the three end up singing karaoke, much to Sheldon's dismay.
