1.65. A man was walking down a road when a stone lodged
itself between his foot and his sandal. He leaned against a pole and, with
his head down to watch, he shook his foot to dislodge the stone. Another
man came up and broke the first man’s arm in three places. (RB)

1.65 answer: The chap shaking his foot to dislodge the stone was leanig
against a metal light pole. The other fellow came along and thought that
the pole had become ‘live’ somehow; he thought the first fellow was being
electrocuted (and that the muscles in his hand had contracted and he
couldn’t let go). So the second fellow rushed over and whacked the first
one on the arm, hard. He apologised for it afterwards. (A true story, from
an Australian newspaper.)
