Can Sandra Bullock do anything wrong? The actress had a busy day yesterday, including an appearance on The Daily Show With Jon Stewart and getting to make her Gravity costar George Clooney laugh during a special screening of their new flick in NYC. While at The Daily Show, Sandra took time to get in a few playful jabs at her handsome costar while joking with Jon that it's hard to buy George's character in the film. She asked Jon, "So you buy me flying, but you don't buy Clooney being a sort of affable ladies' man? I could see that." George and Sandra have been getting a lot of time to trade jokes on one another over the past few weeks while they've been promoting their project. Earlier this week, the pair joked on the red carpet at the Gravity premiere in the Big Apple, where George revealed that he's never dated Sandra because she used to go out with one of his best friends. "There's a certain bro code, you know what I mean?" he said, adding, "I've known her a long, long time."
