Quote from Bert in the episode Spoiler: Gary Dies
Bert: Do you have an identical twin brother? Stuart: No. Bert: Okay, I have two questions. Stuart: Just two? Traveler: I've only got a few seconds to explain this, so you gotta focus. Stuart: Who are you? Bert: First question. Traveler: I'm you from another stream of reality. Bert: Well, that answers that. Second question... Traveler: Listen to me. This apocalyptic nightmare that you are living in, it can be avoided, it never has to happen. Bert: Okay, now I have, like, six questions.
