Your favourite guest stars on Supernatural EVER!
Over 14 seasons and clocking up a massive 300th episodes we have had a huge array of guest stars. Some have had longer appearances than others and some actors just come in for ten minutes of the opening scenes to set the tone of the episode. So with those thoughts in mind, which of over the years have those guest stars left a lasting impression on you guys. I will limit the amount just to make it slightly harder for you, so give me your top ten and of course a reason why for each.
Fire away!
