How my brain works, or 1-to-R and other rational progressions

Driving home last night I heard a commentary by Walter Cronkite on the Battle of the Bulge (SO good...god I love old-fashioned reporting like this). This made me long to continue watching Band of Brothers (got the DVD set for Christmas; y'all know how I feel about this show). Then, as I watched, one of the scenes reminded me of "Death of the Ball Turret Gunner."

Is this the trajectory of most post-holiday musings? Should I be alarmed?
