Reasons to work all night

# Act out your version of a company takeover.

# Find a way to change everyone's password to "chrysanthemum".

# Around 3:20am, play connect-the-dots with lights still on in other office buildings. Keep going until you see a small woodland creature.

# Sneaking in the boss's desk could land you an unexpected promotion.

# Draw stick people in all the landscape pictures on the walls, and in the morning, be the first to point out "what a terrible thing that someone did this to such beautiful works of art".

# Go into the other gender's bathroom without fear of being caught.

# Run up and down the hallways screaming, hoping security will come so you can have someone to talk to.

# Leave prank messages on the CEO's voice mail.

# Finally, a chance to live out a dream and pretend to be your boss.

# Elevator surfing!
