A friend of mine reminded me tonight some of the greatest and freakiest horror characters in history: The Gentlemen. 
They starred in a BUFFY THE VAMPIRE SLAYER episode in 1999 before the turn of the century.
They were a group of demons that roamed from town to town and needed human hearts to stay alive.

I always wondered with Joss Whedon based the GENTLEMEN on.. Perhaps Slenderman? Maybe the men in black.. Not the Black Eyed Children, since the BEKs are more of a new found group of paranormal entities..

If you don’t remember the episode HUSH here’s a clip of the gentlemen and the creepy song that accompanied them.

Sleep well..
