Wow; I hope you don't mind if I steal that life jacket line.
The sheer volume of perfectly rational nonsense that is done flies in the face of what many consider common sense. It's nice to have a simple nonsequitor to jump to for when the need arises.
I like it. It's a shame the Apollo program got rid of the shark repellent from Mercury (at least, as far as I can tell) [1]. It would have been even better to say that NASA took shark repellent to the moon.
I guess taking a life raft to the moon is about as good.
I bet they also had lifejackets. Who needs lifejackets in space?!
