President Obama and citizen Letterman look like they got along famously today during the taping of tonight's show. Even though he's attained rock star status amongst many, word is that Barack didn't take his appearance to the marquee, like Sir McCartney, Phish and TV on the Radio have in the past.

While he's been on the program in the past, this is his first time as the president, and this is the first time the show has had a sitting president as a guest. As such, he'll be the only guest for the hour long program. Spoiler alert: Obama told the host, "The main reason I'm here? I want to see that heart-shaped potato" an audience member brought in. After tossing it to the stage, the woman agreed to let the leader of the free world keep it; he declared: "This is remarkable."
