The best screams you will ever hear are just a click away.
Step 1: The Set Up
choose one of the pranks below
jingle bells (less common)
my favorite one its less common as the one bellow but makes the person concentrate (make sure they don't see the title)
lots of people have seen this so be careful so they don't figure out what your doing!
now run through your chosen prank with the speakers very low or off so you are prepared.
Step 2: The Play
don't forget to take a video and link it on the comments i will embed it here.
if you liked it don't forget to vote.
