Later Penny walks in on Shamy to bring a sewing kit they asked for, very promptly getting high marks. They claim to need the kit since Sheldon split his paints bending over. Penny tells him he'll be sore tomorrow as she leaves. Penny got fifteen points, while Bernadette is shipping them a sewing kit through Amazon (company)|Amazon.

Penny walks in on Leonard who is working on a brain teaser using a seating chart arrangement which he finds fun. Penny received the same puzzle from Amy and threw it away.

Raj also had to drive Sheldon all the way to the Arcadia, California|Arcadia train store and he didn't even go in. All four of them were given plastic rings that they were told to hold onto.
Sheldon and Amy are tallying up results when the gang breaks in on them demanding to know if they are testing them to be in their wedding. "Yes/No!" Leonard tells him that he didn't even want to be his best man. Howard admits that he figured out that they were being tested and he gets extra points for it.
Sheldon enters the comic book store as Stuart offers to sell him a cappuccino which someone had left.

Stuart has never been called the best anything and he also gets a present from the groom.
In the cafeteria, Leonard is still working on the seating puzzle. Sheldon comes over to apologize saying that he violated their trust. He tells them that Stuart is his best man and they are still all invited to the bachelor party at Costco.

Then she gets pissed that her best friend didn't ask her to be her maid of honor.
Howard is telling Amy that despite what was she did was wrong and cruel, Bernadette finds it oddly appealing. If Amy calls her, she'll do be anything in the wedding party, maid of honor, hit woman.... Penny comes storming in saying that as her best friend she should be her maid of honor. Amy rushes over to hug Penny ecstatically shouting, "BESTIE!!"
At Wolowitz's Sheldon apologizes to Stuart, but he was best man for two whole days. Sheldon offers him the job of flower girl until they remind him that they have Halley. Howard hasn't yet told Bernadette that she isn't going to be maid of honor. Amy volunteers which is fine with Penny.

- Caroline Preece at Den of Geek! - When Amy reveals that she’s still in the process of choosing a maid of honor for the wedding, she asks Sheldon to change the subject should it come up in conversation with their friends. He somehow manages to throw them off the scent despite some close calls, and the couple later decide to use detailed metrics to decide who should be in the wedding party. This is of course pretty arbitrary because, as the audience, we know that Sheldon would never choose Raj or Howard to be his best man, and Amy has been in love with Penny for multiple seasons now...It’s particularly charming when the two of them can be as goofy and terrible as each other, like when Amy rejoices in the idea that she can hurt her friends’ feelings without taking on any of the responsibility. It’s also a testament to how thoroughly quirky the couple are that none of their friends twig until the last minute.

- Sheldon: My mother is pushing for my brother, Georgie, to be my best man, and I hate to disappoint her again. I already rejected her savior and her LinkedIn invitation.

- Leonard: I just talked to Sheldon. He apologized for the tests and asked me to be his best man.
- Penny: Uh, great after all you’ve done for him, he should’ve asked you.
- Leonard: And Amy’s you’re best friend. I’m sure she’ll come around to her senses and pick you.
- Penny: Okay, she’s not my best friend. We’re not twelve. If she wants Bernadette to be her maid of honor I don’t really care.
- Leonard: Sounds like you care.

- Leonard: You okay?
- Penny: No, my best friend didn’t ask me to be her maid of honor. I’m pissed.
[In apartment 4B, immediately afterwards]

- Amy: So she still wants to be my maid of honor?
- Howard: Maid of honor, hit woman, whatever you need. Make the call.
- Penny: [Storms in.] Look, I know this is your wedding and you can do whatever you want, but if you think anyone but me is gonna to be your maid of honor then you’re an idiot since you are my best friend.
- Howard: Too late, Bernad..
- Amy: [Pushes Howard aside and runs over to hug Penny extremely happily.] Bestie!!
