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

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.

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."

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?

Sheldon: I'm not Sheldon. I'm the Flash. And now I'm going to the Grand Canyon to scream in frustration *takes two quick steps* I'm back

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.

Very funny episode, one of my fav! Zack is a very funny character --and played by a good actor. Too bad he didn't showed up anymore in the series.

Hope this continues as one of the best comedy series from USA. Far better than TwoAndAHalfMen.

I had a Sheldon moment when watching this episode I saw they showed Dead Horse Point as the Grand Canyon. I just had to point it out and ruin it for everyone.

I have to agree with Matt from the US Season 4 so far has been Sheldon Centric, iMHO a little much, Jim Parson's Emmy is well deserved, but that should not take away from the talent of the rest of the team, IMHO they all deserved an Emmy
