In this special segment, some of George's past guests explained why late comedian George Carlin was so important.
"He was like the Gordie Howe of stand-up," said Toronto-based standup comedian and writer Tim Steeves.
"He just kind of reminded me of that uncle you weren't suppose to like," said comedian Jean Paul. "That uncle — that favourite uncle you weren't suppose to like, and you weren't suppose to like him because he actually experienced life and called everybody on their bull---t."
