All right, so that last test was seriously disappointing. Apparently, being civil isn't motivating you, so let's try it her way, all right, fatty? Adopted... fatty! Fatty, fatty no parents?

GLaDOS:

And...?

Wheatley:

What?

GLaDOS:

What exactly is wrong with being adopted?

Wheatley:

What's wrong with being adopted? Um, well, uh, Lack of parents?

GLaDOS:

[to Chell] For the record, you are adopted and that's terrible. Just work with me.

Wheatley:

Some of my my best friends are actually orphans.

GLaDOS:

Also, look at her, you moron. She's not fat.

Wheatley:

I AM NOT A MORON! Just do the test; just do the test.
