Yesterday we learned that BOOM! Studios was kicking off a new imprint called BOOM! Town, under which they'll release "literary comics" projects as well as merchandising. One of the first products they'll release is a Too Much Coffee Man coffee mug, featuring Shannon Wheeler's famous creation.
Its appearance changes when you fill it with a hot beverage, though I'm not sure which of the above mugs represents the before and which one represents the after (I assume an empty mug = death, and thus the skull).
