Vulture correspondent Julie Klausner sat down with Community’s Gillian Jacobs to explore the depths of the Internet in a little game we like to call YouTube Rabbit Hole. Basically, you just watch a bunch of videos on YouTube, and follow the thumbnail links on the right of whatever you’re watching to other videos, until your afternoon is gone. Join Julie as she exposes Gillian to her first-ever Harlem Shake (Gillian is unimpressed), while Gillian exposes Julie to the last cyst-popping video she will ever watch voluntarily.
