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.".
