Funny story about a cockatoo that likes to scream this on the train. Personal note: I had a cockatoo that would scream: "Unlock the door!" whenever he was in a cage. Once he chewed the screen off the window and got out while I was running an errand. When I came back, I found a note on my door from Animal Control letting me know they had him. When I went to pick him up, there was a group of about ten people standing at the door to the office and the corridor (it was at City Hall), they were all there to hear him say "Unlock the door! Unlock the door! You forgot your daughter!"
