Channel Stephen Hawking and ask him WTF is happening?

Shave tRUMP's head.

Probably a bank rob

I suppose the first thing I would do is rush out and find everyone I even mildly dislike or worse and reposition them with others around them in uncomfortable or questionable positions. That way when they wake up there's some decent shockvalue. I definitely would force myself to stay awake so I could take as much advantage of the situation as humanly possible. Is technology still functional during this "time-out"? If not than I would take advantage of the downed security cameras at some casino, swipe some keys and hit up the vault. Otherwise, I'm sure I'd think of plenty of ways to keep myself entertained.

1. Become rich
2. Make everyone lose their keys
3. Take selfies in tons of places that I would normally never have access to.
4. Study how time being frozen effects atomic particles.

I think I'd spend the day gathering evidence of a few people I can think of lies and wrong doings to make sure that got what was coming when things were back to normal. Not personal revenge, though in one case there might be personal satisfaction, but people in positions of power who think they are untouchable.

Wow, some great answers. And here my sophmoric brain went to tatooing a penis on Trumps face, and shaving off whatever that is on his head. Then it got darker. Rounding up all the crooks in DC, zip-tying them together back to back in a circle and delivering them to Mueller's office.....or Gitmo. In my defense, I have the flu.

The mind boggles

I can't say. My machine is almost ready!!!

Go to St Louis, find a Porsche dealer and drive the most expensive 911 like a mad man.

Play a crazy elaborate prank on a bunch of high-profile people all at the same time. It might involve a bit of light theft to accomplish, which I'd be hesitant to do, but I could probably like label stuff and who it belongs to or something so it could all be returned.
