Thomas Jefferson was one kinky dude.

Seriously! Not only did he knock up one of his slaves, but he knocked up two of his father-in-law's daughters!

You probably know about Sally Hemings. If not, well, she was the slave that Jefferson had an illegitimate child with. What I thought was so surprising is that Sally Hemings was, herself, the illegitimate daughter of a slave owner. That slave owner? John Wayles, father of Martha Wayles Skelton Jefferson, who would later become Jefferson's wife.

Yep, that's right. Jefferson not only knocked boots with one of his slaves, but was also married to that slave's half-sister. Not only did I find this pretty unbelievable, but so did interviewer Diane Rehm.

You can listen to the interview by clicking here (Real Audio) or here (Windows Media). The webpage regarding this interview can be seen here.

And, yes, Diane Rehm does have a weird voice that sounds like Hans Moleman. It's caused by the disease spasmodic dysphonia.
