And I believe the title comes from the idea that one hour of TV programming has 22 minutes of content, with the rest being commercials. (It is also a play on the name “This Hour has Seven Days”, a Canadian TV show from the mid 60’s)
There was an old news program called “This Hour Has Seven Days” or somesuch (referring to a week’s worth of news being crammed into an hour-long show), which is where the joke comes from.
