The image is a meme featuring two blocks of text and a photograph of a man with a somewhat bemused or matter-of-fact facial expression. The top block of text reads, “‘You shouldn’t leave your car unlocked, someone could steal it.’” The bottom block of text, which appears to be the man’s response, says, “It ain’t got no gas in it.”
The humor in the meme comes from the implication that the man is unconcerned about the possibility of his car being stolen because it has an empty gas tank, which he suggests would deter potential thieves. The man's facial expression and the casual way he addresses the situation contribute to the comedic effect.
