In the Firefly episode "Out of Gas" (1x05) Wash wires up a large, red button for the captain to press if he needs the crew to return to the ship. When he shows it to Mal he says, "When your miracle gets here, just hit this button." When Alan left the Firefly (2002) set after the series was canceled, he took that button as a keepsake. When Joss Whedon announced that he would be searching for a way to bring the show back as either a series or a feature film, Alan sent him the button with a note that said, again, "When your miracle gets here, just hit this button.".
