Uncle Bob and Archie Wood
Yahoo Group: Archie and His Friends. (Don't miss the pictures and mp3's!)
(Weird, this group doesn't seem to be in google's database even though it's been around since 2001... had to search Usenet to find it.)
Well, google sees MY page, so I'll add a few keywords here for the benefit of other nostalgic 'Peggers who are "seeking yet cannot find":
Uncle Bob and his dummy, Archie Wood, were the stars of "Archie and His Friends", a daily TV show ran in Winnipeg during the 1970's and 80's. It featured other puppets such as Tammy True, Petite the Dog, the weasely Marvin Mouse, the occasional appearance by Grampa Wood, and the frightening Robby the Robot.
I remember the crew were always playing jokes on Uncle Bob. Here's an anecdote about "Robby the Robot". Robby was a cardboard box with big teeth that looked not unlike a squarer, flatter domokun:
You're right about the crew during Robbie segments. The favourite gag was to try to grab Bob's hand in Robbie's 'teeth'. They would hold pretty tight if you caught him just right as he was trying to retrieve a dime, a script, or whatever he'd put in. The person that was operating Robbie was crouching down behind the robot and very close to where Bob would stand. Many times, his belt would get undone, his tie removed, shoeslaces tied together, etc, etc. while the camera was on the robot.
