President Obama is on Ellen today, and in clips the show released, he gives host Ellen DeGeneres grief about her famous Oscars selfie—because before she broke the record for most retweets, Obama was the one who held it. "I don't know if you know this, but I was aiming to break your record of retweets and I apologize for doing it," DeGeneres said. "I heard about that," Obama replied. "I thought it was a pretty cheap stunt myself. Getting a bunch of celebrities in the background, you feeding them pizza." The satellite appearance—Obama's first time on the show as president, Entertainment Weekly notes—is yet another attempt by Obama to remind people about the March 31 deadline to sign up for ObamaCare.
