My sister and I send out a ridiculous Christmas card to all of our friends every year. While I agree the typical, serious Christmas card is a waste, we try to at least make people laugh. For example this year, we photoshopped our drunken/stupid/not-normal faces to Mount Rushmore and renamed 'Rushmore' with a play on our last name. The front reads "Merry Christmas Ya Filthy Animal!" and the back "...And A Happy New Year!" with a picture of Kevin giving a shit eating grin. It usually goes over pretty well.
