The Avengers Season 6 Episode 33 Bizarre

Found wandering in a snowy field Helen Pritchard claims to have seen a man who was supposed to have been a corpse but was very much alive. This leads Steed to investigate the Happy Meadows funeral parlour and the cheery Mr. Bagpipes Happychap. Unfortunately the undertakers seem unable to keep their 'stiffs' from walking and Steed has to arrange his own funeral in order to find out more, though ultimately he and Miss King do get a send-off that is out of this world!
