Michelle Obama & Ellen Stir Up Trouble at Costco

As the first unofficial stop on her book tour, Michelle Obama and Ellen Degeneres visited a Costco to sign copies of Obama's new memoir Becoming. This being Ellen, Degeneres had to cause some trouble, handing out copies of her own book and offering the former First Lady a Sharpie to sniff. "When they go low, we get high," she joked. While their Costco trip didn't quite live up to the hijinks of their iconic CVS run, it was still hilarious, especially once Degeneres broke out a keyboard.
