VIDEO : First Lady Michelle Obama Impersonates President Barack Obama

First Lady Michelle Obama sat down with Stephen Colbert Tuesday to dish on Beyoncé, sleepovers at Buckingham Palace and her love of french fries. But the most unforgettable moment came when the first lady decided to share her impression of President Barack Obama, who she's been married to since 1992. Michelle launched into her impersonation, mimicking the president as he would answer his daughter's question about a daily event.
