Jimmy Kimmel premiered a special edition of his "Lie Witness News" segment in honor of President's Day.

"There are a lot of presidents who we don't know much about so we sent a camera crew out to today to tell people that Franklin Delano Roosevelt died," Kimmel explained.

The problem is...FDR was born in 1882 and died in 1945.

But that didn't stop people from remembering him fondly from his "Twitter account" to his cameo in "Pearl Harbor."

Watch the video and how much average Americans don't know.
