Joe Pera Watches Internet Videos With You

The clock on Joe's headboard follows along in real time for the first 6 minutes of the episode. Beginning at 1:45 AM, it reaches 1:51 AM around the 6-minute mark.

In Joe's glasses you can see multiple times the phone reflected, and it is just a solid green because they add any video content later in post-production. The phone is actually serving as a mini green screen. This is further revealed by the fact that multiple times their dialogue does not match what is playing on the screen.
