X-Files is pretty popular and well known.

I am older than The X-Files, but also we have these magical things called recordings, so we can actually watch things after they were aired on TV!

When I was a kid our washing machine and dryer were under the stairs. My brother once managed to climb between them and hide behind the washing machine, even when I gave up and told him to call out, I couldn't find him, mostly because I just couldn't believe anyone could fit in that space so couldn't imagine it being a hiding spot.
