Late Show with David Letterman - President Barack Obama, Dave Letterman

President Barack Obama's appearance on Monday's Late Show gave David Letterman his highest ratings in four years, according to The Hollywood Reporter.  

Letterman topped The Tonight Show with Conan O'Brien by a whopping 195 percent. The last time he had numbers that high was when Oprah Winfrey visited in 2005.

Obama's appearance on Letterman, however, did not net more viewers than his March appearance on The Tonight Show, when it was still hosted by Jay Leno.
