A story from the old days, before I joined my dojo.
A brand new 3th kyu got his brand new hakama.
During warm-up, they were doing that exercise where you spread your legs and stretch your arm as far as possible to the other side of the body.
The only person that wasn't spreading his legs was the 3th kyu, for which he got a remark.
Turned out that he stepped in one pipe with both legs.
