Two kids were trying to figure out what game to play.
One said, “Let’s play doctor.”
“Good idea.” said the other. “You operate, and I’ll sue.”

A well-respected surgeon was relaxing on his sofa one evening just after arriving home from work. As he was tuning into the evening news, the phone rang. The doctor calmly answered it and heard the familiar voice of a colleague on the other end of the line. “We need a fourth for poker,” said the friend.
“I’ll be right over,” whispered the doctor.
As he was putting on his coat, his wife asked, “Is it serious?”
“Oh yes, quite serious,” said the doctor gravely. “In fact, three doctors are there already!”

Patient:   “I have an ear ache.”
Physician:

2000 B.C. – Here, eat this root.
1000 A.D. – That root is heathen, say this prayer.
1850 A.D. – That prayer is superstition, drink this potion.
1940 A.D. – That potion is snake oil, swallow this pill.
1985 A.D. – That pill is ineffective, take this antibiotic.
2000 A.D. – That antibiotic is artificial. Here, eat this root.
