"Where are we?" Depp (as Captain Jack) asked after staggering onstage. Bailey replied, "Disneyland."
Blinking thoughtfully, Jack responded, "Never heard of it," before he started throwing out grapes into the audience.
"Grape! Grape! It bounced, don't pick it up. I hate grapes. I despise the rotten little things," Depp said while distributing the freebies at the Disney fan event.
"I came to sing you a song!" he declared, before being ushered off the stage by Bailey.
"Dead Men Tell No Tales" recently wrapped production, and is slated for release on July 7, 2017.
The fifth installment in the franchise stars Depp along with returning stars Orlando Bloom (Will Turner) and Geoffrey Rush (Captain Barbossa), and franchise newcomers Javier Bardem, Brenton Thwaites and Kaya Scodelario.
