I think "grab a spoon" works in context as simply a strange thing to say, but it does have an origin. It's from the pilot episode of Friends. Recently divorced Ross is worrying that there might only be one woman for every person, and he lost his. Joey scoffs at this, claiming that's like saying there's only one flavor of ice cream. After listing a variety of flavors, he tells Ross to "grab a spoon."

How Incredibly Evil Stepmother Bishop knows about this line from Friends is anyone's guess, but I'm pretty sure most of her expressions are relatively modern, so her speech raises several questions even without it.

Also curious is shooting for the moon and hitting the stars. The idea is that, even if you miss the moon (a lofty goal), you'll hit the stars. I don't think that's how space travel or goals work, and If all we had to do to reach distant stars was miss the moon, faster than light space travel would be both solved and very strange.
