Lt. Col. Sheppard and Teyla in “Unfinished Business”

Lt. Col. Sheppard

[Typing in Rodney's password, who thinks Sheppard can't remember it] 16431879196842. See, it doesn't take a genius.

Teyla

I-it doesn't?

Lt. Col. Sheppard

1643 is the year Isaac Newton was born. 1879, Einstein. And 1968...

Teyla

The year Rodney was born.

Lt. Col. Sheppard

Never underestimate the size of that man's ego.

Teyla

Weren't there other numbers?

Lt. Col. Sheppard

42.

Teyla

What is that?

Lt. Col. Sheppard

It's the ultimate answer to the great question of life, the universe and everything.
