You hope you never see a sphincter...
1. Anywhere you'd eat.
That didn't deter, however, artist Atelier Van Lieshout from creating the the Bar Rectum,
which "takes its shape from the human digestive system: starting with
the tongue, continuing to the stomach, moving through the small and the
large intestines and exiting through the anus...The anus itself is part
of a large door that doubles as an emergency exit."
Yummy.
2. Anywhere you keep your lipstick.

The larger image is even more unsettling.
