'Now tell me' Dog is a Bichon Frise wearing sunglasses in the back of a car, the image says 'Cool story bro' then continues with 'Now tell me' followed by a funny statement in which the Dog asks a question to presumably the person driving the car. The meme is usually posted in a comments section that started on Facebook.

Popular examples of the dog include 'Cool strory Bro, now tell me, did you leave any cookies in the car' and when the dog asks questions about popular video games, movies or TV shows.
