Penny wants to start her own business, making hair clips she calls ”Penny Blossoms”, but she has no marketing, manufacturing or commercial knowledge, and receives help from the guys, especially Sheldon. However, when they get an over-night order with 1000 Penny Blossoms, it’s going to take a lot more than “hard work” to complete the order within the 24 hours they have. Meanwhile, Penny convinces Sheldon into drinking his first cup of coffee, but the results are Sheldon becoming hyperactive and acting as if he was using drugs.
