Nelson Shanks is an artist who got the incredible opportunity to paint former President Bill Clinton's official presidential portrait for the National Gallery of Art.
That's quite an honor. So, naturally he decided to stick it to Clinton.
"This is the 37th time I have spoken to you from this office" is how President Richard M. Nixon began his final television speech on August 8, 1974 -- 40 years ago.
He was, and still is, the only sitting U.S. president to resign from office.
