So, which one is Ronnie?
Ronnie Corbett is the small one
Ronnie Barker is the middle sized one
John Cleese is the tall one
Wikipedia says Ronnie told people he was the shortest commissioned officer in the RAF.
Great story, but maybe it's just what he told people.
P.S. It turns out the guy in the middle, a.k.a. the middle class, was Ronnie Barker, Corbett's comedy partner, a.k.a. the other Ronnie.
From left to right. John Cleese (The tallest), Ronnie Barker (In the Middle) and the late Ronnie Corbett (the smallest).
