Quiz Kid Donnie Smith: Want to know the common element for the entire group?... I'll tell you the answer: I'll tell you, 'cause I had that one. I had that question... Carbon. Carbon. In pencil lead, it's in the form of graphite and in coal, it's mixed up with other impurities and in the diamond it's in hard form.
[Jimmy Gator impression]
Quiz Kid Donnie Smith: "Well... all we were asking was the common element, Donnie... but thank you for all that unnecessary knowledge... haha, kids! Heads so full of useless knowledge. Thank you. Thank you." And the book says: "We may be through with the past... but the past is not through with us!"
[to Thurston]
Quiz Kid Donnie Smith: And... no, it is not dangerous to confuse children with angels!
