Great job, Gordon! Throwing that switch and all, I can see your MIT education really pays for itself.

Dr. Isaac Kleiner: We can't leave without Lamarr. She's around here somewhere...
Alyx Vance: Come on, Dr. Kleiner. We can find you another pet headcrab.
Dr. Isaac Kleiner: No! There's only one Hedy!

Time, Dr. Freeman? Is it really that time again? It seems as if you only just arrived. You've done a great deal in a small time span. You've done so well, in fact, that I've received some interesting offers for your services.

Rise and shine, Mister Freeman. Rise and... shine. Not that I... wish to imply you have been sleeping on the job. No one is more deserving of a rest, and all the effort in the world would have gone to waste until... well, let's just say your hour has... come again.

Dr. Eli Vance: A-hem! Alyx, why don't you take Gordon along and give him some practice with the Gravity Gun?
Alyx Vance: Sure. C'mon, Gordon. Let's go have some fun.
Dr. Judith Mossman: The Zero Point Energy Field Manipulator is not a toy, Alyx.
Alyx Vance: Ugh, let's get outta here.
