I recall an interesting story in a biography of Bertrand Russell.
He was visiting friends one week during the autumn months, when all of a sudden they needed to dash from the house for an afternoon. Worried at being left alone, Russell asked; "who shall make my afternoon tea?!" (It being a well known fact that Russell MUST have a cup of tea every afternoon, lest he become cranky) In response, his hosts replied: "You shall, dear Bertrand!", to which he replied; "But I do not know how!".
Confused by the situation whereby such a brilliant mind could not make his own afternoon tea, his hosts proceeded to lay out all of the utensils and pots etc and made a detailed, step by step guide on how to make the tea and then dashed off to their destination.
When the arrived several hours later, Russell was in an awful state and the tea remained un-made.
The stories of impractical philosophers are endlessly amusing
