Quote from Hal in Chad's Sleepover
Dewey: This in no way justifies what you said before. Hal: Chad, I want to show you a little project I've been working on. Look at this. [Chad stops chopping with the ax] You see where I took my pen and I filled in the letters that needed to be filled in. The "O's," the "A's," the "E's," the "G's." Chad: The "Q's," the "P's," the "D's" and the "B's"? Hal: Of course. Dewey: That was you? Chad: What about the nines? Hal: Yes. Chad: What about the circles and the percent signs? Hal: Absolutely. Otherwise you'll be left with that horrible feeling of uncompleteness.
