The Oberon, that reminds me of a recruiting ad for the Metropolitan Police back in the 1970s. In those days, before it was deemed 'discriminatory', male recruits had to be at least 5'10" tall, whereas female recruits only had to be taller than 5'4"......
Or, as the advert stated:
"What's the difference between a PC and a WPC in the Met? About six inches"
I'm sure that they could have expressed that rather better.....
