A man driving home from the bar gets pulled over by a police officer.
Officer: “Do you know why I pulled you over?”
Driver: “I’m guessing you think I was drunk driving.”
Officer: “Tell you what, my shift is ending so if you can spell the alphabet backwards, I’ll let you go.”
Driver: (very quickly) “ZYXWVUTSRQPONMLKJIHGFEDCBA.”
Officer: “Wow, I couldn’t do that sober.”
Driver: “Me neither.”
