Nice analogy on forever smacking his head as he attempts to pass through doorways.
I honestly hope he gets to a door way that gets pissed off of him hitting them and smacks him right back with such supreme force that he is knocked unconscious for a length of time (in scenario-land only of course ..or maybe not)
Pretty cool imagery though of animated, personified doorways ...the start of a screenplay maybe ..LOL.
Then there is this other screenplay that was made into a classic some 60 yrs or more ago ...the line rattles around in my head ..."if I only had a brain" (or at least one that I used on occasion). Hey there Danno ..are yer ears ringing.
