When Parks and Recreation star Adam Scott set out to pull off The Greatest Event in Television History the first three times, he turned to three of the biggest actors in Hollywood:

Jon Hamm…

Amy Poehler…

Catherine O’Hara/Jon Glaser/Kathryn Hahn/Chelsea Peretti/Jason Mantzoukas…

And now, he has recruited a comedy VIP for the fourth Greatest Event in Television History: Paul Rudd.

EW has learned that the star of This Is 40 and fan of Mac and Me will appear alongside Scott in the latest installment of the only franchise brave enough to attempt to re-create the opening credits of ’80s TV shows. (And, yes, Jeff Probst will be returning as the host.) The first Greatest Event boasted a shot-for-shot remake of Simon & Simon‘s title sequence, the second took on Hart to Hart, and the third got a little Too Close for Comfort. No word on what classic show is up for re-enactment this time around, but Adult Swim just released the photo above to EW that should fuel the speculation game until the new special airs Thursday night, Jan. 23, at midnight on Adult Swim.
