Stan Kirsch(Highlander)

Shocked to hear of the passing of Stan Kirsch, who played Richie Ryan in the tv series of Highlander, where he was the sidekick to Connor McLeod(Adrian Paul) before meeting an untimely end(he had his head taken from him by accident by Connor) He also appeared in a cameo performance in Friends in an episode called 'The One with the Ick Factor' playing Ethan, a young man dating Courtney Cox's character Monica who lied about his age because he was a senior high school student. He was only 51!
