In a psychiatrist’s office:
A man comes in and says,
“Good day to you. I am King Arthur. I demand to Speak with the doctor.”
The nurse says wearily,
“You are not King Arthur, Mr. Crankleberry. Please sit down.”
Mr. Crankleberry exclaims,
“I am! It was God himself who told me I am King Arthur.”
Another patient stands up angrily,
“I certainly did not!”
