What time does the library open?” the man on the phone asked.
Annoyed, the librarian composed himself before he answered.
“9 am,” came the reply. “And what’s the idea of calling me at home in the middle of the night to ask a question like that?”
“Not until 9 am?” the man asked in a disappointed voice. The librarian began to get angry.
“No, not until 9 am,” said the librarian. “Why do you want to get in before 9 am?”
“Who said I wanted to get in?” the man sighed sadly. “I want to get out”.
