Things I hold dear... (in the respect of all things nerd)
Finding a long-lost missing lego and/or weapon to complete that long incomplete toy
Putting up a new display shelf
Getting an NES game to work without blowing in it.
Rearranging the collection
Perfect paint and tight joints on an action figure
Getting my wife to watch any Star Wars film
Dropping a nerd reference on my classes and having a student "get it"...they very often don't.
Putting fresh decals on a G1 Transformer
Finding out any classic kid property is getting a reboot AND finding out the reboot is awesome (Nickelodeon Ninja Turtles / GI Joe Resolute are nice calls)
Getting a really good nerd series in its entirity on a snow-day with the wifey...Spaced, Lord of the Rings.
Watching On-Demand episodes of Clone Wars and Adventure Time with the son during 3 AM feedings.
Positive feedback on ebay
Fixing an O-ring on a broken Joe
THAT IS ALL... :)
