Best Things to Do with "watch"
Have a pillow fight with yourself in your bedroom. Watch your mom's reaction when she walks into your room.
Super glue a quarter to the sidewalk and watch from a distance to see if anyone tries to pick it up.
Put googly eyes on everything in the fridge, (without anyone knowing of course) and watch as someone opens it.
With a friend, take two symbols(the instrument) and clash it in another friend's ear, and make their ears pop, and when they come back, mute the TV, and talk with no sound, and make them think they lost their hearing and watch them freak out.
Fill an empty coke bottle with soy sauce and Sprite, stick it in the fridge for someone. Watch what happens, it's hilarious.
