The greatest trick the Devil ever pulled was convincing the world they should work in an office.

When I'm bored at work, I like to look at what other people do to fight boredom at their jobs. The answer? Pranks. According to my extensive study on the subject, all you have to do to make a great office prank is be a dick and have spare time. Here are the best office pranks on the Internet:

1. The air horn chair.

Sure, it requires some patience. But the payoff is, well, loud.

2. The Internet-Explorer-Is-Your-Only-Option.

This is just cruel. Shudder.
