Great TV Shows That Nearly Were: Part I...

The Other Woman refers to me as a Walking Filth Bucket but she can be equally disgusting, so I am inventing a new game.

It's called Great TV Shows That Nearly Were and the rules are simple: take a real TV show and switch one letter or add and remove one letter to make it a more interesting TV show. For additional points, you can also give a brief listing for the show.

Here is an example:
Great Canal Journeys: A well-famous actor enjoys another exciting adventure of discovery with his lovely wife.
Great Anal Journeys: See above.

This could run and run...
