Oh dear - this scene always makes me laugh, unfortunately.

I remember reading a novel or short story once where a bloke reluctantly has his mum to stay with him for a few days.

One night, they decide to kill a couple of hours by choosing a video to watch...

Can you imagine anything you'd less like to watch with your mum?

Cronenberg's Dead Ringers, maybe?

I remember watching this scene in a theater. Believe me, in context nobody was laughing.

Watching it now, I see how the amazing, limited selection of shots fosters the frightening feeling I recall -- of hiding in that closet, watching, helpless, sure that the nut job will discover I'm there.

Great scene.
