I'd wish for the remote from the movie Click, only with the ability to actually rewind and let me go back and edit things, and also make save points so that I'd be able to go back and change something to see what it'd be like but still be able to just snap back to my own normal life with the push of a button. And also I wouldn't be an idiot with it like Adam Sandler was in that movie. He bitched about not having time and about being tired, and he fast forwarded past stuff so he could finish work and get better quicker.
The remote let him stop time.
Somehow he never just paused shit and finished his model for work or pause it and get some sleep.
I'm pausing time to steal bags of cash from bank vaults and rewinding back with this weeks winning lotto numbers. Also, I'm going to try and see what would be different if I had made some different choices in life, like not wrecking my first car.
Also would be cool if it would let me view movies had they been different, but that's a bit much to pull off in one wish. Like if certain actors had taken roles instead of turning them down. Will Smith playing Neo in the Matrix for instance, or Bruce Willis as the bad trainer cop in Training Day.
