That's a joke, but real time capsules often aren't as interesting as they could be because the makers of them put things that they think are important (like a portrait of Teddy Roosevelt if he was President of the US at the time) rather than details of what their daily lives were like which they didn't think of including.

You say that as a joke, but it would say a lot about contemporary American culture.

Just think about the gender roles on display, a women attacks her husband and gloats that society will side with her. Not to mention the meta-layer, the celebrity worship that would compel someone to preserve this particular document of all things.
