Everyone knew that one big kid in school who was constantly playing "pranks" that simply involved physically hurting other people ("You just punched me in the kidneys!" "Ha! Gotcha!"). Well, those kids grow up, and often go their entire lives without ever discovering the difference between a "practical joke" and "randomly harming other people just because." Fortunately for them, an entire industry has emerged to help them raise their game.

#6. Ultimate PC Prank Master

The Ultimate PC Prank Master is a $29.95 USB device that, when connected to any computer, proceeds to cripple it in several random and annoying ways.

Gadgets and Gear
The only way that USB drive could be more obnoxious is if it were full of bootleg Dane Cook routines.

It's basically like having a particularly malicious virus, so really you can achieve the same result by taking a regular USB drive to a public library computer and then lending it to a friend. Presumably this was created by someone who went through a devastating malware attack and thought "Hilarious!"

"More people need to go through this, for no good reason."

The available "pranks" include jerking the cursor around, turning caps lock on and off indiscriminately and typing nonsensical snippets of text at random times, essentially recreating the experience of being 14 and on MySpace all over again. You can control the frequency with which these things happen through a series of buttons on the device itself, which also features a convenient time delay setting so that it doesn't start working immediately after you volunteered to clean the 10 years of dust off the back of your friend's desktop computer.

Gadgets and Gear
This is the perfect hiding place, because nobody knows what half those cables do.

So, apparently, at some point the victim is supposed to find this piece of destructive technology you've secretly placed in their machine, say "Oh, you card!" and ... hand it back to you? Because if he, say, angrily steps on it and tells you to fuck off forever, you just lost $30 on a pretty shitty joke.

And if Proposition #297 passes, most of the skin on your back.

The device won't press "Enter" or close unsaved documents, because that would be too easy -- it's not meant to get your friends fired, it's only supposed to drive them to suicide. And hey, if you can get them to pick up the phone and dial the number for the suicide hotline, that makes them the perfect target for the next "hilarious" joke ...

#5. Wrong Number Generator

The Wrong Number Generator does exactly what the name implies -- it makes the victim's phone call the wrong number. So it's a simple gadget designed to exasperate not one, but dozens of people at the same time: the "friend" whose phone it's installed on, the multiple strangers said friend will accidentally interrupt whenever he tries to make a call and the phone company employee who will eventually get yelled at over a nonexistent problem. It's a miserable time all around, for only $89.
