The gallbladder is a small organ nestled under the liver. It acts as a bag to store and concentrate bile, a dark green to yellowish brown fluid produced by the liver.
The gallbladder is not very funny, but from ancient times into the 19th century yellow bile was one of the four humors in the humoral theory of medicine.
