I said if before, but really, look at him. That's astronaut Lee Morin during his first spacewalk on mission STS-110, outside Atlantis back in April 2002.

I can imagine him going "La-di-da, la-di-da, la la, I'm in space, fixing this thingie, La-di-da" while screwing screws in and out at the International Space Station.

If this is not the best job in the world, I don't know what is.
