Here's what Michelle said about her experience in 2012 on Letterman -
"At another point, Letterman held up a photo of Mrs. Obama shopping at Target in low-key garb.
"That’s my Target run. I went to Target," she said. "I thought I was undercover. I have to tell you something about this trip though. No one knew that was me because a woman actually walked up to me, right? I was in the detergent aisle, and she said — I kid you not — she said, ‘Excuse me, I just have to ask you something,’ and I thought, ‘Oh, cover’s blown.’ She said, ‘Can you reach on that shelf and hand me the detergent?’ I kid you not.”
As the audience laughed, she went on, “And the only thing she said — I reached up, ’cause she was short, and I reached up, pulled it down — she said, ‘Well, you didn’t have to make it look so easy.. I thought, as soon as she walked up — I was with my assistant, and I said, ‘This is it, it’s over. We’re going to have to leave.’ She just needed the detergent.”
