The Boss says, "I told you to get a sign-off from marketing before you sent this around." Dilbert says, "How vivid is your false memory of that conversation?" The Boss says, "It's plenty vivid." Dilbert says, "Were unicorns involved?"
Dilbert's Mom pours a cup of coffee. Dilbert has a unicorn horn growing out of his forehead. Dilbert says, "At least I can count on my mom to love me, despite my horn." Dilbert's Mom says, "Yes, of course, albeit not as much as before." Dilbert says, "How much less?" Dilbert's mom says, "Don't worry my love of unicorns practically covers the gap."
Dogbert stands on the table and says to Ken the Skeptic, "If your controlled tests have never found psychic powers, how do you know the tests work for that sort of thing?" Ken glares and folds his arms across his chest. Dogbert says, "Isn't that like using a metal detector to find out if there are unicorns in your sock drawer?" Ken says, "No!" Later that night... Ken thinks, "A skeptic checks all the drawers." He runs a metal detector over a chest of drawers.
