Remember those mysterious “NETFLIX IS A JOKE” billboards that popped up in Los Angeles and New York earlier this month? Well, we finally have an explanation.

As previously thought, Netflix itself was behind those weird ads, ahead of this weekend’s announcement of a run of stand-up specials.

The streaming platform dropped a trailer announcing upcoming stand-ups from Jerry Seinfeld, Chris Rock, Dave Chappelle and Ellen Degeneres.

In the clip, the aforementioned comics hilariously pop up in scenes from popular Netflix shows like Stranger Things, House of Cards, The Crown and Orange is the New Black. For example, Seinfeld is inserted into the Oval Office, as Frank Underwood is talking into the camera, as he does in House of Cards. That’s just one of the hilarious spots though. See them all in the video above.
