I have shaken hands with Trotsky at one remove. That is, I have shaken hands with a fellow who shook hands with him. This person — I am sorry, but I totally forget his name — gave an address to the Socialist Society at University College, London, ca. 1964. He had been with Trotsky in Mexico. And I shook his hand.

I have shaken hands with Hitler at two removes — but anyone at NR can make the same claim (via David Pryce-Jones).
