This is truly hilarious:

“Occasionally, (Einstein) would take rambling walks on his own, which could be dicey.  One day someone called the Institute and asked to speak to a particular dean.  When his secretary said that the dean wasn’t available, the caller hesitatingly asked for Einstein’s home address.  That was not possible to give out, he was informed.  The caller’s voice then dropped to a whisper. ‘Please don’t tell anybody,’ he said, ‘but I am Dr. Einstein, I’m on my way home, and I’ve fogotten where my house is’ (Walter Isaacson, Einstein: His Life and Universe [Simon and Schuster, 2007], 439).”

I have been accused of being absent-minded before, but nobody can I say I’m this bad!
