My favorite was when telephone numbers were six digits and given as a set of 3 two digit numbers, forcing you to transpose each of the two digit numbers to write it down.
A system almost designed to cause problems.
But, to be honest, the French expressing 99 as (4*20) + 19 really is more exquisitely bizarre.
