Here, Rusty, next time you "take the cats out........."

I went to school with a guy who was 6'8" (and later replaced him in a band).

He could not walk through a 6'8" standard door without timing his step to be almost exactly mid-stride when he was in the doorway.
My friend owned a stereo shop and hired a guy exactly 7 foot tall. Like you say he had to time his steps going through the normal size door. My buddy said he hired him so he could dust the top shelves. lol
