Toughest spelling test joke

"I've just had the most awful time," said a boy to his friends. "First I got angina pectoris, then arteriosclerosis. Just as I was recovering, I got psoriasis. They gave me hypodermics, and to top it all, tonsillitis was followed by appendectomy."

"Wow! How did you pull through?" sympathized his friends.

"I don't know," the boy replied. "Toughest spelling test I ever had."
