Mr. Krabs: Alright, Plankton! It's Eugene Krabs, here, with, What's-His-Name! Now come on out!
Plankton: I can't.
Mr. Krabs: Come on outside, and take what's coming to you!
Plankton: I really can't come outside!
SpongeBob: Why not?
Plankton: Because I'm already out here, you bumbling bottom feeders! Open your eyes for crying out loud!

Trivia: Spongebob's first words as a baby were, "May I take your order?"
