Invented by
Thomas Jefferson in 1796, the
Second Butt Hole is an additional anus created in order to alternate pooping. While maximizing
efficiency, the Second Butt Hole also provides relief to the primary butt hole, so that you don't get sore from all that pooping.
The Second Butt Hole is most famous from its appearance in the film Titanic. Ben Stiller has also reported being an avid fan of the Second Butt Hole.
