"Backseat Driver" joke

A man who is driving a car is stopped by a police officer.
The following exchange takes place... The man says, "What's
the problem officer?"
Officer: "You were going at least 75 in a 55 zone."
Man: "No sir, I was going 65."
Wife: "Oh, Harry. You were going 80." (The man gives his wife
a dirty look.)
Officer: "I'm also going to give you a ticket for your broken
tail light."
Man: "Broken tail light? I didn't know about a broken tail
light!"
Wife: "Oh Harry, you've known about that tail light for weeks."
(The man gives his wife another dirty look.)
Officer: "I'm also going to give you a citation for not
wearing your seatbelt."
Man: "Oh I just took it off when you were walking up to
the car."
Wife: "Oh Harry, you never wear your seatbelt."
The man turns to his wife and yells, "SHUT YOUR MOUTH!"
The Officer turns to the woman and asks, "Ma'am, does your
husband talk to you this way all the time?"
The wife says, "No, only when he's drunk."
