I watch old McDonald's commercials on the net

I first watched the old McDonald's commercials from the 1980's on RetroJunk & YouTube when I was 11 to 12 years old. Those commercials were aired on American television before September 10, 1989 Sunday. I didn't know that Grimace, Hamburglar & Birdie the Early Bird can talk in every commercial. Speaking of Birdie, she's voiced by Russi Taylor which I know her as the current voice of Minnie Mouse.
