I've been watching reruns of Mister Ed quite a bit lately. It's a good show from the early 1960s, about a talking horse. However, Mister Ed only talks to (and in front of) his owner, Wilber Post (played by Alan Young, who would later go on to voice Scrooge McDuck on DuckTales). But Mister Ed often talks on the phone with people, and sometimes talks to others who are unable to see that a horse is talking to them.
I first saw this show on Nick at Nite. It was taken off the line-up a few months after my household got cable, and the channel had a farewell marathon for the show, entitled "Au Revoir Mister Ed". Some of my favorite episodes include the one where the cast goes to Hawaii and Mister Ed surfs, the episode where Mister Ed drives a car, and the episodes with George Burns and Clint Eastwood. I recently saw the episode "Ed the Ventreloquist", in which Roger Adision walks in on Wilber and Ed having a conversation, and becomming convinced Ed can talk, until Ed convinces Adison that Wilber was just being a ventreloquist.
Watching many episodes recently, it seems like Mister Ed doesn't really get much screen time in many of the episodes, focusing more on the Posts and their neighbors. But maybe that's just me.
I remember for years wondering the name of the actor who voiced Mister Ed. The credits said "Mister Ed as Himself", and at first I thought that was the voice actor (it's the stage name for the horse, though the horse's real name was Bamboo Harvester). It wasn't until I looked up the show on Internet Movie Database when I saw that the name of the voice of Mister Ed was Alan Lane.
