Two old men were sat on a bench outside a
nursing home having a
chat. “How are
you, Richard?” asked George.
“I’m not feeling too good today, I’m
utterly
exhausted,” replied
Richard. “I’ve pulled a muscle, and it’s
killing me.”
“I’m
surprised that a pulled muscle makes you feel so tired,” said George.

Richard
yawned and said, “Well, it does if you pull it a hundred
times in one
night.”
