When Chief Justice John Roberts flubbed the oath, I joked to someone that conservatives will milk that for years claiming Obama's not really president. Within 12 hours, they were already starting on the Internet. Luckily, Obama actually reads the Internet, so they did a do-over to put that one to rest.

On the other hand, it turns out the Yo Yo Ma/Itzhak Perlman performance was synched to a tape, so that's probably close enough for impeachment.
