Please be advised that a noticeable taste of blood is not part of any test protocol but is an unintended side effect of the Aperture Science Material Emancipation Grid, which may, in semi-rare cases, emancipate dental fillings, crowns, tooth enamel, and teeth.

Look: we're both stuck in this place. I'll use lasers to inscribe a line down the center of the facility, and one half will be where you live, and I'll live in the other half. We won't have to try to kill each other or even talk if we don't feel like it.

Who are you? What is that? Oh, What's that? What's THAT? What is THAT?

Remember, the Aperture Science Bring Your Daughter to Work Day is the perfect time to have her tested.

Where are we going? Are you coming back? What's that noise? Is that a gun? Do you smell something burning? Ooooohh... what's in heeeere?
