Marshall: Robin has changed her mind.
Ted: No, Robin doesn't change her mind.
Marshall: Except that she does. Remember she used to claim to hate white-guy funk bands? Yet, at the farewell performance of my band, The Funk, the Whole Funk and Nothing but the Funk, there's Robin, nodding her head and shouting out requests for "Give Up the Funk."
Ted: I think she was nodding in response to my question, "Do you want to leave soon?" And she was legitimately suggesting that you give up the funk.
