Dev Topics has a great list of 101 Great Computer Programming Quotes. I like many of them but here are a couple I loved.

“That’s what’s cool about working with computers. They don’t argue, they remember everything, and they don’t drink all your beer.”
(Paul Leary) (Though I would substitute Chocolate;)

“Never trust a computer you can’t throw out a window.”
(Steve Wozniak)

“Most software today is very much like an Egyptian pyramid with millions of bricks piled on top of each other, with no structural integrity, but just done by brute force and thousands of slaves.”
(Alan Kay)
