Must have a Rex line check!
Or an oral check with the JCAB in Japan
Seriously, I was asked the number of white stripes on the piano keys of a 45m rwy and a 60m rwy, the dimensions of the white stripes (not just the length) and the varying standards between the old and new touchdown markings. I had to pinch my leg to prevent myself from laughing out loud at such ridiculous and irrelevant questions.
