Howard：They're on me today, boys.

Raj：You're paying? Have you been selling your sperm again?

Howard：No, I'm celebrating.

As we speak, the space shuttle is docking

at the International Space Station where it will deploy the Wolowitz ZeroGravity Waste Disposal System.

Raj：Get over yourself. It's a hightech toilet.

Leonard：Just think. Thanks to your hard work,

an international crew of astronauts will "boldly go where no man has gone before."

Howard：Is that supposed to be funny?

and the play on words involving the doublemeaning of the verb "to go" suggests that Leonard is mocking your efforts in space plumbing.

Howard：Okay, make your little jokes,

but of the four of us, I'm the only one making any realworld contribution to science and technology.

Raj：He's right. This is an important achievement, for two reasons.

Number one... and, of course, number two!

Sheldon：Clever! Playing on the use of cardinal numbers as euphemisms for bodily functions.
