Other places one might find inside jokes:
A website run by U.S. Cellular.
Nearly anything having to do with Muppets.
Or Homestar Runner.
Or Walt Disney World Today.
Or Wesleyan University.
Or The X-Files.
But not in some parts of Canada, apparently.
A GameSpot forum.
An interview show.
The New York Times.
Where can you send your inside joke?
