A couple got "Rick Rolled at their own wedding. The groom's friend comes up to do a reading, and he starts by talking about their friendship as actors and writers - but then begins reading the lyrics to "Never Gonna Give You Up".
Everyone seems to get the joke, including the bride and groom who laugh along. It works because the friend plays it completely straight. One of the other groomsman right next to him realizes immediately what their buddy's doing before the bride & groom catch on soon after. He covers his face to hide his laughter since they're at a wedding.
