The Gregory Brothers are best known as the creators of Auto-Tune the News/Songify This, but they also have another series of videos that could easily translate to at-home fun.
The game is called "WikiWars" and it requires two contestants with their own laptops. The players are given the same page on which to start (i.e. "baseball") and then race to reach a completely unreleated page (i.e. "The Treaty of Versailles") using only hyperlinks found within Wikipedia. Contestants are allowed to use Ctrl-F to find specific words on a given page, but they can't search within Wikipedia itself. As The Gregory Brothers document, the results are high-stakes and often hilarious.
There are more WikiWars videos on The Gregory Brother's YouTube page.
