Nice ones, although the Fruit Oaty bar one seems more like one for the Comedy/Parody section along with all of those classic Firefly humor moments such as:
Mal:"Everyone has the right to live and... kill people,"
~~~
Inara: [With shocked expression] "Jayne Cobb, you're talking about Jayne Cobb"
~~~
Jayne: "We could really use some grenades right about now!"
~~~
Simon: "My sister's a ship, we had a complicated childhood"
~~~
Book: "Killing yes, but it (the Bible) is a little fuzzy on the subject of kneecaps"
~~~
Inara: "What did I tell you about barging into my shuttle"
Mal: "That it was manly and impulsive"
Inara: "Yes, only the exact word I used was 'Don't'"
~~~
Mal: "This is your Captain speaking, we might experience some slight turbulence and then... explode"
...time lapse...
Jayne: "Explode, I don't wanna explode!"
