this is very funny. i used to be in the Air Cadets ( in canada ) and when we were learning to march, if you "thought" too much about it you would do exactly what the artists error on ...we called it "bear marching" ..it was a rather hilarious thing snd no doubt would receive a dose of yelling from the corporal or sergeant running drill.
"tick tocking" was what we called it in our sea cadets corp. It is surprisingly hard to get it right without practice (and then I guess less conscious thought)
