Jack Ryan, the man who created Barbie and Ken, as well as Hot Wheels and other classic Mattel products, was a very naughty boy. In fact he was “a ‘full blown seventies-style swinger’ who patronised ‘high class call girls to streetwalkers’ in his quest for excitement”. Not that any of that really matters, even if his horniness may have led to Barbie’s impossible physique, it just makes for a silly story.
