The NES is not connected to anything except the controllers. That counts for 3 things, one power connection, one audio connection and one video connection.
The other four things wrong are the people. None of them are looking at the monitor, besides that they're ugly, the mom forgot to put the `tard helmets on the boys, dressed them like clowns and nobody wears a round necked sweater over a collared shirt unless it's laundry day and there's nothing else to wear or they have a strangle-me-during-clothed-sex fetish.

I almost forgot to mention, that's a Commodore monitor. The a/v RCA connections are in the front under the flip-down cover at the bottom and it has to be open for those connections to be made. There are RCA connections in the back but they are separated composite video (chroma & luma - what has now become s-video, BTW) and not compatible with the NES composite video output.
