K is for Klutz

In this cartoon short, a woman uses the toilet at a party, only to discover that her stool refuses to be flushed. The stool starts making squeaking noises as it moves on its own towards its "creator". After the woman seemingly manages to flush it, she continues to hear the squeak. As she inspects the toilet, the stool is revealed to be clinging to the ceiling above her; it drops down, re-entering her anus at high speed. She bolts upright, stunned, and then falls down dead, as the stool slides out her mouth on a stream of blood. Other party guests enter and find her body.
