True story, this happened to me this morning:

-Woke up thirsty like the dickens!
-Got myself an absurdly large mug of Green Tea.
-Went back to my nice warm bed and took a sip.
-Immediately fell asleep, mug still in hand, which, of course, poured half of it's contents onto my bed.
-Woke up from the cold Green Tea, and Set the mug aside on the nightstand by the foot of my bed.
-Pulled the sheets off to assess the damage when my blanket smacked the cup off of the night stand, which then caused the mug to empty it's remaining contents onto my floor, school-bag, and hoodie.
-... Needless to say, I was NOT PLEASED.
