It's a typical night so the boys are playing laster obstacle chess, but Sheldon can't join... he has a package to deliver to Penny! Penny just got in some glitter for her new business - selling Penny Blossoms, which are flower-shaped hair berets. When Sheldon sees how unoptimized her manufacturing process is, he cannot help but put in his two sense. Soon Sheldon as a small assembly line going and the two of them are singing sea shanties and really pumping these things out. However, when the rest of the guys walk into Penny's apartment they all get involves in the process.
Leonard then sets up a website for Penny Blossoms, and although it looks like a 13 year old girl dsigned it, quickly gets an rush delivery order from the Gay and Lesbian Alliaance of East Rutherford, New Jersey for 1000. The guys have until tomorrow (even though it's Saturday night and there's no delivery on Sunday...shhh) to make 1000 and they end up spending all night making them. They use the power of coffee and Sheldon tries the "drug" himself for the first time. At the end of the epiosde, they complete the berets in time but get an email from the alliance asking for another 1000. Everyone is out and Sheldon takes off wearing a Flash costume to go get more coffee. He'll be back before this banana hits the ground!
