Episode Notes

  • The title references the Justice League costume group which the guys invite Penny and Zack to be a part of.

> Sheldon's Knock

When the guys go to Penny's apartment to apologize for their ridiculing of Zack, Leonard knocks on Penny's door three times and Sheldon feels compelled to say "Penny." Later, Sheldon, dressed as the Flash, knocks on Penny's door frantically, saying "Penny" each time.


Raj: I've said this before and I'll say it again: Aquaman sucks!

Zack: You want to go with em?
Penny: No.
Zack: Okay, see you later.
Penny: Wait, w-w-wait-wait-wait, youre ditching me to go look at comic books?
Zack: Are you mad at me?
Penny: Im not happy.
Zack: Milk Dud?

Zack: Hold on. The costume came with a black wig.
Penny: No. I'm not wearing it. It looks stupid.
Zack: Come on. We're trying to win a contest here.
Penny: Forget it. I'm not wearing the wig.
Zack: Honey, there is no "I" in "Justice League."

Stuart: So are you guys coming to my New Year's Eve costume party?
Sheldon: Of course. We're coming as the Justice League of America.
Howard: Switching it up from last year when we came as the Justice League of America.
Sheldon: To that point, it occurs to me that we might have an opportunity to finally snare Best Group Costume if we shore up our weak link, which is clearly Leonard as Superman.
Leonard: Hey, I got new boots this year. Guaranteed to add three inches.
Sheldon: That's sad. Let's ask ourselves, is there anyone we know who would make a more manly and convincing son of Krypton?
Stuart: Than than Leonard in high-heeled boots? Howard's mother in high-heeled boots?
Sheldon: I was thinking specifically of the gentleman over there moving his lips as he enjoys the latest exploits of Betty and Veronica.
Leonard: Zack?
Howard: He is the only person we know with actual muscles.
Leonard: You can't replace me with Zack.
Sheldon: Why not? Penny did it.
Howard: Yeah, she seems happier. Why wouldn't we be?
Zack: Score. I got an Archie, Betty and Veronica, and a Jughead. All set for my weekend number twos.
Sheldon: Congratulations. Zack, how would you like to be Superman?
Zack: I don't know, sounds like a lot of responsibility.

Zack: You know, I saw this great thing on the Discovery Channel. Turns out if you kill a starfish it'll just come back to life.
Sheldon: Was the starfish wearing boxer shorts? Because you might have been watching Nickelodeon.


After Penny and Zack get back together, the guys make fun of his lack of intelligence. When Zack realizes what's they're doing, he leaves the apartment and Penny scolds the guys for bullying him. The guys go over to Penny's apartment to apologize to him and invite Zack to the comic book store with them. At the store, they realize Zack would make a great addition to their Justice League group for Stuart's New Year's Eve costume party.

When the guys settle on their costumes, Raj is stuck being Aquaman. The guys buy a Wonder Woman costume for Penny, but she is not interested. After Penny relents and dresses as Wonder Woman, she refuses to wear the wig that goes with the costume. Leonard eventually talks Penny around, who reveals that she's unhappy because she's not in a proper relationship and isn't really interested in Zack.

At the comic book store, the group wins the costume party. When it strikes New Year's Day, Zack is kissing Penny, though she's looking over at Leonard. On their way home from the party, the guys witness an ongoing car theft, but decide against acting like superheroes and walk in the opposite direction.
