would much rather have a pause button due to how much i would be able to do with it comparatively to being able to rewind. With being able to pause i could put things in odd places as a prank (eggs above peoples heads, cars in buildings, etc.). I would also seem very smooth because every time I screwed up talking to a girl I would be able to stop and think about what I should say thus having me never say anything stupid. I would also be able to take anything I wanted from anywhere and never be caught. I could simply walk into the bank and take all the money from the vault.
