As a very young girl, my wife can remember General Charles de Gaulle visiting her infant school in rural France and bending down to shake her hand. She recalls him being very tall and a bit scary.
I can't claim having met anyone as famous, but did get a kiss from punkette chanteuse Hazel O'Connor once.
Belatedly: I reckon I have a fairish claim to being within a few degrees of separation from Hitler (told of in my post #685). It occurs to me that I have a closer connection with Stalin.
Thinking about it, as well as the Bolsheviks, I can probably get to Nicholas II in less than six: I once met the grand-daughter of the last (pre-Revolutionary) Ataman of the Kuban Cossacks. So me to her; her to her grandmother, her grandmother to her grandfather (he was killed during the Civil War, so never met his grand-daughters), and given that he was CO of the army which supplied troops for the Imperial Lifeguard, and also Governor of the Kuban Region, I'd put money on him having met the Tsar, although as I write I don't know for certain. That'sWhich puts you at three from Hitler, and at five from Stalin. And, so at one more from Khrushchev, Malenkov, Beria (maybe less, if Ribbentrop had met some of them), and in fact all important Bolshevik leaders, like Lenin, Trotsky, Zinoviev, Kamenev and Bukharin.
Never mind Hitler, you're only four degrees away from me You - Mcririck - Mayall - Broadbent - David Jason - me.I met the late JOHN MCCRIRICK, who was in The New Statesman with the late RIK MAYALL, who was in the Government Inspector with JIM BROADBENT, who was in Only Fools and Horses with the late LENNARD PEARCE, who once met ADOLF HITLER.
