Colbert asked Obama how she feels about the lives of candidates' spouses on the campaign trail. After a perfect pause, Obama says she has "no sympathy" for the spouses, particularly if they plagiarize.
The interview gets even awesomer, and Obama demonstrated her Barack impression. You get to know his mannerisms pretty well after 23 years of marriage—the next guy to play him on SNL should give it a try.
Oh, and she also talks about what Beyoncé's—her fellow "low-key lady"—is really like.
Michelle, we miss you already.
