Second Butt Hole 

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.

"Man I was so wasted last night, I was shitting all morning. Thank God I have the Second Butt Hole"
