LONDON -- The world of trolling and well-executed pranks is a competitive one, but this week we have a clear winner. Step forward, Malcolm. The best part about Malcolm's note -- which was shared on Reddit on Thursday -- is how his super-neat handwriting lulls you into a false sense of security. You start off thinking he's probably done his neighbours a kind favour and rescued their parcel or something, and then bam -- that last sentence catches you completely off guard. As it turns out, though, Malcolm isn't really a bad guy. He's just an epic prankster. Well played, Malcolm. Have something to add to this story? Share it in the comments.
