Out of Gas
Of course Science Channel has to air one of my favorite episodes of Firefly just as I'd decided that I would be a Responsible Adult and go to bed on time. So it's all their fault I'm still awake.
Wash: "When your miracle gets here, you just pound this button once, it'll call back both shuttles."
Trivia: The red button Wash rigs to call the shuttles back and return the crew to Serenity was removed from the set on one of the last days of filming by Alan Tudyk, as by that time the cast and crew knew they were being canceled. Scenes on the bridge for Out of Gas were filmed the next day, and the button is noticeably absent. Alan then mailed the button to series creator Joss Whedon, with a note saying "When you get your miracle, just hit this" (quoting Wash's line). Whedon was hoping to revive the series, which he did, in the form of the film Serenity.
Wash: "I am a leaf on the wind - watch how I soar."
Damn you, Whedon!
