“[Calvin, who has the chicken pox, calls Susie on the telephone.]
Susie: Hello?
Calvin: Hi, Susie! It's me, Calvin! I was wondering if you'd like to come over and play.
Susie: Why, sure! Boy, I don't think you've ever invited me to...
Calvin's Mom: Calvin, what are you doing?
Calvin: Nothing, Mom. Go away.
Calvin's Mom: You're contagious! You can't have anyone over to play!
Calvin: Shhhh! Shhhh! You'll spoil the whole thing! I was going to trick Susie into catching... HEY! OW! LET GO!
Susie: [Hanging up the phone] Any chance of getting transferred, Dad?”

“[Calvin and Hobbes are playing Scrabble.]
Calvin: Ha! I've got a great word and it's on a "Double word score" box!
Hobbes: "ZQFMGB" isn't a word! It doesn't even have a vowel!
Calvin: It is so a word! It's a worm found in New Guinea! Everyone knows that!
Hobbes: I'm looking it up.
Calvin: You do, and I'll look up that 12-letter word you played with all the Xs and Js!
Hobbes: What's your score for ZQFMGB?
Calvin: 957.”
