Poor old Comic Sans, always getting a bum rap, as in this photo of a pair of dueling passive-aggressive door-notes at an unnamed Fortune 500 corporation. Funny: I fault signmaker the first more for the excessive use of exclamation points; and number two needs a refresher course in capitalization — “lemonade stand” is only a proper noun if you’re talking about the Apple ][+ game.
(Thanks, Fipi Lele!)
