Gravelface,
My favorite episodes are out of gas, and war stories. I especially like the commentary on war stories by nathan and Alan.
Currently, I have one Serenity shirt that i picked up on my annual pilgrimage to the Monroeville Mall (where dawn of the dead was filmed). I recently found a place that makes reproduction Jayne battlegear, i may invest in a jayne style belt, holster, and bowie sheath. Would be kind of cool.
