Quote from Bernadette Rostenkowski in the episode Spoiler: Bert is Magic
Bernadette Rostenkowski: [munching] So, what's up, buttercup? Stuart: Well, this is gonna sound crazy, but we've got this machine that allows you to travel between alternate universes. Kripke: And we just need a wittle abwacadabwa to jump-start the damn thing. Bernadette Rostenkowski: Sorry to disappoint you, but I'm all out of abracadabra. Kripke: Word on the street is you're wike a worwd-wenowned sowcewess. Bernadette Rostenkowski: Used to be. Stuart: What happened? Bernadette Rostenkowski: Not that it's any of your business, but the Wizards Guild of America claimed I used my powers while we were on strike. Kripke: What were you on strike for? Bernadette Rostenkowski: Better dental, residuals for eternal spells. It's ridiculous. We were out for six months, and basically, everyone got a handful of magic beans.
