It's 6AM. and you are about to throw the alarm clock out the window. It's too cold out, you're tired, you had one glass of wine too many last night, you've really got to clean your house, and, most importantly, you haven't had some real bonding time with your couch lately.
"Just call in," you tell yourself. "They can get by one day without me."
So, in your best sick voice, you leave a near-death sounding message for your boss and throw in a cough just to make it believable. Ferris Bueller has nothing on you!
