Give Me Genius

My favorite neighborhood coffee place always has a "sandwich board" on the sidewalk. Most businesses use this form of free advertising to promote one or more of their products. The one that Think Coffee has in front always has these completely random funny sayings on it. A few weeks ago it had quote on it that literally had me laughing out loud. It said:

"To the person who I threw scalding hot coffee on...I am sorry, I thought you were on fire."
