The act of placing ones thumb into the rectum of an animal followed by removing it and placing it directly into ones own rectum followed by removing said thumb and inserting into ones own mouth while humming a tune.
While Dan was frolicking in a meadow, he came upon a sheep. While noticing that nobody was watching he decided to stick his thumb in the sheep's ass, remove it and place it in his own ass. For reasons still unknown, he then sucked on his thumb and hummed a little tune on his new Stinky Kazoo!
