Ghosts, with all their limitations, can still be invaluable friends. By being able to go through walls, disappearing on command, being invisible and floating in mid air, they can help you in many ways:

Spying: They can go see what your competitors are doing and report back to you.

Blackmailing: You can easily gather monetary gain from people’s embarrassing secrets. This is your chance to use that proverbial “fly on the wall”.

Recon: Ghosts can’t really transport anything heavy, so they are pretty useless at stealing gold bars or bags of money for you. But they can look around for you to find safe combination, passwords, names on a list, PIN numbers, etc. No need to learn complicated and illegal hacking techniques with you’re friend with a ghost.

Pranks: With ghosts, the potential for pranks is endless. A head coming out of the toilet, an empty suit chasing your friends, body parts in the soup, a torso peeking through the wall… You’ll never be bored again!

Pretending to have psychic powers: With otherworldly connections, your ghost friend can tell you about your customer’s deceased family members to make you look like the big shot who charges the big bucks.

Preparation: One day, you might have the chance of turning into a ghost yourself, so learn the trick now!
