Fallon reemerged on the Tonight Show on Wednesday (16 November). As he was introduced out onto the stage by announcer Steve Higgins, Fallon joined the band The Roots and a choir dressed in white church robe attire as they sang, "He's alive! He's not dead!"
The comedian then said he wouldn't leave the planet until his job was done.
In the opening monologue, the host also poked fun at other world topics by adding his own "death" into the discussion.
"When they heard I died, Ticketmaster kicked me out of line for Taylor Swift tickets," Fallon said.
"And I go, 'This is terrible. This is awful."
Fallon jokingly added: "Right after it happened, though, I was so touched that NBC immediately called and asked, 'How can we turn this into another Law & Order'?"
