Please report any ghost activity you may notice in the London Underground. We want to keep those pesky spirits out of there since they aren't paying for the trip.

Just imagine how many times the owner was questioned about ghosts. He just had to put up this sign.

It seems some ghosts are wondering about. Should you come across any of them, please inform us and we will handle it somehow.

Don't risk kids, stay in the safe zone! ALWAYS!

I wonder how they harvest such poop.
