Every day life can get boring, so why not spice it up?
After all, anyone can pull a prank on April 1, but why should you confine yourself to just one day?
Make your own “milk spill” with a piece of plastic, glue, and soap.
Reverse the tab on the top of the can and then watch their frustration build.
Just don’t forget that you did it and then accidentally throw open the door. Otherwise, this is a classic.
Or you could put the horn...
