PULLED A MUSCLE
"How are you feeling today, Little Johnny?" asked Suzy.
"I'm not feeling too good today, Suzy, and exhausted," replied Little Johnny. "I've pulled a muscle, and it's killing me."
"I'm surprised that a pulled muscle makes you feel so tired," commented Suzy.
Little Johnny yawned and said, "Well, it does if you pull it a hundred times a night."
