Joe Alaskey of the 80's

I was unaware of Joe Alaskey's stand-up comedy career of the 1980's. He was known for his various impersonations of famous people such as Jackie Gleason, Don Knotts, William Shatner and many more.
Today, Alaskey provides many voices for various animated shows. He has provided service for Warner Bros taking on the roles of many classic Looney Tunes such as Bugs Bunny, Marvin the Martian, Sylvester, Tweety and Daffy Duck.
I think it was a wise choice on Warner Bros part to cast him with roles originated by Mel Blanc. In the following clips, you can hear a little bit of Mel Blanc's tone in his impersonations.
