Quote from Hal in Mono
Hal: Okay, Jamie. Here we go. None of Mommy's monster germs are in here. But don't get too comfortable in the big boys' room. It's only temporary. Dewey: He's never leaving, is he? Hal: What? No. This is just until it's safe to go back into our room. Reese: You said the same thing when Dewey moved in. Are you gonna take him back now that your ringworm's better? Hal: I told you we are still on yellow alert with that!
