BEST PRANK EVER!!!
Film a toilet after it has been flushed (tank filling up)
when you have lots of people around and one person goes to the toilet, get everyone around the TV and put the tape on so it will show the toilet's tank refilling with water, the person then thinks that everyone has just seen them go to the toilet and they get very embarrassed
hahha
Oh I have the best Idea for a prank, but I'm saving it for senior prank...
See we have Standardized testing, and on those testing days, Seniors don't have to go to the first half of the day, well when I'm a senior, I go during the moring and let the air outta the Drivers Side tires of all the Juniors and Sophmors who drive to school. Be funny when everyone comes out and has to call AAA or switch out the tires or something...
