Pull Over Sir!
Paddy is driving home from the pub and gets pulled over by a police officer.
The officer says ''Good evening sir, do you know why I pulled you over?''
Paddy replies ''I'm guessing you were thinking I was drunk driving.''
The officer informs Paddy that he's 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 Paddy says, ZYXWVUTSRQPONMLKJIHGFEDCBA.''
The officer who is impressed by the oration now believes that Paddy is clean and states,
''Wow I couldn't have done that sober.''
Paddy replies ''Me neither!''
