TEXT: Scene: The apartment. Raj: Water Demon. Howard: Ice Dragon. Leonard: Lesser Warlord of Ka'a. Sheldon: Not so fast. Infinite Sheldon. Leonard: Infinite Sheldon? Sheldon: Yes, Infinite Sheldon defeats all other cards and does not violate the rule against homemade cards because I made it at work. Leonard: Do you understand why people don't want to play with you? Sheldon: No, although it's a question I've been pondering since preschool. Leonard: Hey. Zack: Hey. Leonard: Hey. Penny: Hey, your copy of Science magazine was in my mailbox. Leonard: Oh, thanks. Penny: Mm-hmm. Zack: Check it out, all about planets this month. Leonard: That's an atom. Zack: Agree to disagree. That's what I love about science, there's no one right answer. Leonard: So, you and Zack again, huh? Penny: Yeah, yeah, me and Zack again. Zack: Were we here earlier? Penny: Okay, we should, we should go. Zack: Ah, not yet. I want to talk science with the science dudes. Howard: Oh, and the science dudes want to talk science with you. What do you want to talk about, rocks, dinosaurs, our friend the beaver? Zack: You know, I saw this great thing on the Discovery Channel. Turns out that 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: No, I'm almost sure that it was the Discovery Channel. It was a great show. They also said dolphins might be smarter than people. Leonard: They might be smarter than some people. Zack: Well, maybe we can do an experiment to find out. Sheldon: Oh, that's easy enough. We'd need a large tank of water, a hoop to jump through, and a bucket of whatever bite-sized treats you find tasty. Zack: I don't
SUMMARY:
Penny gets back together with Zack. The guys insult Zack's low intelligence which upsets him; however he reconciles with the four and accompanies them to the comic book store. The five enter a costume contest and urge Penny to join in a Wonder Woman costume. She refuses until Leonard talks to her. She reveals that she got back together with Zack only because she did not want to spend New Year's Eve alone. Leonard questions why not with him, prompting Penny to suddenly remember the fun times she used to have with him, convincing her to change her mind. At the comic book store, the group win the award for the Best Group Costume, although it is hinted that they only won because they included a female Wonder Woman. The episode concludes with the six witnessing an ongoing car theft and then scurrying off cowardly despite wearing Justice League costumes.
