HOW TO: Switch the mouse click so that left click will be right click and vice versa for a good, safe, harmless, non-messy, clean, sound April Fool’s Day Prank.
All you need the computer of the victim and about 3 minutes.
First, go to Start->Control Panel->Printers and Other Hardware->Mouse-> (Tab “Buttons”) Check “Switch Primary….” (Near the top)
Now the left click will become the right click (show that menu that usually pops up) while the right click will become the left click. Yeah, the victim does get the hang of it after a while, but it gets really annoying. Which is why it’s so awesome. To fix it, just uncheck the little box.
Oh, and happy first day of April.
