Quotes (26)

Sheldon: I'm sorry, coffee's out of the question. When I moved to California I promised my mother that I wouldn't start doing drugs.

Sheldon: You are effectively paying yourself five dollars and nineteen cents a day.
Penny: A day?
Sheldon: There are children working in sneaker factories in Indonesia who out-earn you.

Sheldon: Camouflaging bald spots. That's primarily a male concern. Perhaps we could expand our market.
Penny: How are flower barrettes going to appeal to men?
Wolowitz: We add Bluetooth.

Penny: Since when do we offer one day rush?
Leonard: Amazon offers one day rush.
Penny: Yeah, but they don't have to glue the books together!

Sheldon: Penny, I'm a physicist. I have a working knowledge of the entire universe and everything it contains.
Penny: Who's Radiohead?
Sheldon: I have a working knowledge of the important things in the universe.


When Sheldon delivers a package to Penny, she tells him it's rhinestones for her plan to start a business selling flower-shaped barrettes, which she calls Penny Blossoms. After Sheldon points out the flaws in her business plan, he and Penny team up to turn this into a viable business.

Leonard, Howard and Raj discover Penny and Sheldon singing work songs and producing the jewelry in assembly line fashion. After the guys offer more business advice, they join the business and set out to improve Penny's manufacturing and marketing operation. After Leonard sets up a website for the items, the guys are surprised when they receive their first order - of 1,000 Penny Blossoms with next day delivery!

The guys spend the whole night in the apartment producing the Penny Blossoms. Sheldon turns to caffeine to power him through the long night. The next morning, when they're finally done producing the order, they receive another order for 1,000 Penny Blossoms. Howard and Raj leave, Leonard goes to bed, while a hyper-active Sheldon runs around the apartment as The Flash.

Did someone notice that Sheldon actually had coffee before? Just watch "The Grasshopper Experiment" (1/8)! ;)

My favorite from this episode where he says "Penny, I am a physicist" and something about having full knowledge of the workings of the universe and everything in it... Penny's response?: "Who's Radiohead?" LOL!!
