Xiao Ming went to a company for an interview. The boss asked, “What are your strong points?”

Xiao Ming said confidently, “I’m especially good at sleeping!”
The boss was stunned: “What does that count as a strong point?”
Xiao Ming: “It’s true! I can sleep until I wake up naturally, never be late, and I don’t need an alarm clock.”
Boss: “Then why did you come to the interview?”
Xiao Ming: “Because last night I dreamed that I got hired, so I came today to confirm it.”
Boss: “...You’ve been hired. The position is: Professional Sleep Testing Officer.”
Xiao Ming said happily, “Great! Can I go back to sleep now?”
