Quote from Tim in The Route of All Evil
Tim: Now it's time for the night-vision goggles. Al: Night-vision goggles? Tim: With these bad boys, you can walk around in pitch black, pick out a burglar. And you'll never whiz wide of the bowl again. What these things do is great, is amplify existing light, like, 2,000 times, just by flicking this switch. [turns Al's goggles on] Al: Oh! Tim: It's like looking into the surface of the sun, isn't it? I'm over here, Al. Over here. Actually, these are... These are designed for using when it's totally dark. Heidi, make it totally dark, please. I'll just switch mine on. There! Wow! Al: Oh, well, now mine aren't working. Tim: I'll just adjust them. Let me grab a screwdriver out of your toolbelt. Al: Tim. That's not my screwdriver.
