Although he had already appeared on five different talk shows over the weekend, President Obama disclosed new information during his first Late Show visit as a sitting POTUS.

“First of all, I think it’s important to realize that I was actually black before the election,” the President clarified to America last night. The humorous comment - a response to the supposed presence of racism in the health care debate - was followed by shock. “Really!... How long have you been a black man?” David Letterman joked.

And while it was clear Obama had an agenda behind his appearance (he said he wanted to see the heart-shaped potato an audience member brought), the host presented his own “Top Ten Reasons President Obama Agreed To Appear On The Late Show.” You can read those after the jump.

Obama will not be the only president to make a late-night stop this week. Former President Bill Clinton will be chatting with Letterman tonight.
