Chris Rock and Dave Chappelle Shared the Stage in New Orleans

The crowd at the Saenger Theatre in New Orleans on Saturday knew they were in for a treat. Chris Rock was set to take the stage for the first of three nights at the venue as part of The Total Blackout Tour, his first stand-up stint in nine years. Following opening acts, Eric Andre and Jeff Ross, a video screen displayed the letters "CR," an obvious reference to the headliner. But, out of nowhere, Dave Chappelle stepped in front of the stunned audience, who greeted him with a standing ovation.

“Tonight, you are all part of a social experiment,” Chappelle told the crowd. "Stranger things have happened in New Orleans." According to Keith Spera of The New Orleans Advocate, the two powerhouse comedians shared the stage for 90 minutes.

Rock learned why it isn't safe to even take a sip of water around Dave.

Meanwhile, the rest of us experienced an extreme case of FOMO, especially after seeing tweets like these:

So, will this "social experiment" eventually lead to a tour in the future? One can only hope.
