Left image: a person in the driving seat is inserting a CD with "Favorite Songs" written on it into the CD player of a car dashboard.
Right image: driver of the car is sad on seeing the person (on the rear view mirror) sitting in the back seat of the car wearing earphones.
The image is funny, as the driver of the car inserts a CD named "Favorite Songs" into the CD player for the passenger, but the driver is sad on seeing the passenger in the back seat listening to something else on earphones instead.
