If it is done like a normal inauguration--live on TV and in front of an audience--what I'm expecting is something along the lines of:
I do solemnly swear that I will faithfully execute the Office of Vice President of the United States, and will to the best of my ability, preserve, protect and defend, you know, THE THING.
But if they do it in isolation, from some secure location, the doddering old fool has a chance to get it right--if they do enough takes.
