Thomas Jefferson was all-around weird.Jefferson's most famous secret was his affair with his slave, Sally Hemings, but he has a host of other weird facts surrounding him. He's credited with introducing a number of foods to the U.S. palate, including vanilla ice cream and macaroni and cheese. He also believed that woolly mammoths still lived in the American West and tasked Lewis and Clark with finding one. He was also fond of revising religion, namely by literally cutting out passages of the Bible he didn't like. He was also petrified of public speaking, giving only two speeches in his two terms as president.

Nixon spied on his brother: Nixon's brother was apparently involved in some shady business dealings, and Nixon so feared that these would reflect negatively on him that he sent the Secret Service to spy on him. We don't need to explain the irony of the situation to you.

Andrew Jackson was almost a bigamist. Both Jackson and his wife, Rachel Donelson, thought she was divorced when they married in 1791. It turns out she wasn't. Oops.

He also apparently thought the world was flat.

Lyndon B. Johnson and his apt name. His face doesn't exactly scream "ladies' man," but Johnson was all about his, um, Johnson. He had a habit of whipping out his member in public. Literally. No shame. He nicknamed it "Jumbo." We're not making this up. He also had numerous affairs with pretty much any female, and his wife was okay with it.

George Washington was really bad at war. Poor George tried, but he was mainly just good at getting the Continental Army to run away during the American Revolution.

He also really did have fake teeth, though none were made of wood.
