Funny prank to confuse anyone who is a slave to the clocks around the house. (or just looks at the time)
Step 1: Wait
Wait untill your victim is away or asleep.
Step 2: Now time for some changes in schedule.
Change the time on all the clocks an hour or so bahead so when your victim awakes he or she will see the time and start to freak out beacause all the clocks are set bahead. then that person will leave for work or school an hour early.
