In one very narrow passageway(that there is another way around) some people would ask loudly, "How does a BIG person make it through here?"
Upon hearing their cue one of my larger helpers in October says, "Like this!" as they run with both arms straight above their heads and pass through very quickly! (Very funny to watch!)
Those 90 degree corners create anticipation and opportunitys to scare.
I like the right side of people coming to such a spot since most people are right -handed and to punch me would then require an aukward across the body , foreshoertened swing of their left fist.
