A man is driving home from the pub and gets pulled over by a police officer.
The office says: “Good evening sir, do you know why I pulled you over?”
The man replies: “I’m guessing you think I was drunk driving.”
The officer informs the man that he is correct and tells him: “Tell you what; my shift is ending soon so if you can spell the alphabet backwards, I’ll let you go without any fuss.”
In a clear and calm voice the man quickly says: “ZYXWVUTSRQPONMLKJIHGFEDCBA.”
Impressed by the quick answer, the officer now believes that the man is clean and states: “Wow, I couldn’t do that sober.”
The man replies with a shrug: “Yeah, me neither.”
