Remember Viscera Cleanup Detail, the former silver-medal Joke Game Flavor of the Month? Here's the Christmas DLC!
Never liked VCD much myself, both because of the concept (super tedious gameplay like that is a bit overwhelming for me anymore) and even if I were into the concept, the "wow look at the funny physics!!!" gimmick that people wanted back then kind of ruins actually cleaning stuff up, and the Funny Physics get kind of dull for me after awhile.

But hey, at least it has a sense of humor!!!!!
