I remember watching a TV news story about the NEAR-Shoemaker probe's crash landing on the asteroid Eros, back in 2001. The quote from it that I love is from one of the mission scientists. It's more than a bit dorky, but it tickles me: "We have no fuel on board, plus or minus 8 kilograms."
I love that "we have no [whatever], plus or minus X" formulation and use it enough to annoy my friends, I'm sure.
