Which is more likely, and why?

I was just trying to figure out which of the following things would be more likely to happen to me TODAY... and also my reasons why I would believe that.

Would I be more likely today to:

1. See a ghost, or see an alien?
2. Have a cold water shower, or touch a spider?
3. Change a flat tire, or wear a crown?
4. Throw a TV from a balcony, or walk barefoot downtown?
5. Walk exactly 19 kilometres, or Drive exactly 19 km?

hmmmm.... anyway, just a few thoughts running through my head.
