An example of this might be one of the following:
- Watching every available episode of Dr. Who - along with a moment of silence for the lost episodes.
- Watching all of Star Trek. Yes even the animated series, the odd numbered moves and even the bastard series Enterprise should be included.
- 10 - 48 hour marathon D&D sessions
- Buliding and maintaing a Geek Blog like this one. (Send me the link)
- Re-reading everything written about StarWars including the stories about the kids and the Technical Manuals.
