Whatever Happened to Tang?

I just read in the paper that the space shuttle Endeavour is bringing to the International Space Station a new marvel of science: a machine that recycles urine into drinkable water.

I wonder if the astronauts will form a line to use such a machine?

BUCK: Um...After you, Flash.

FLASH: Oh, no, Buck, I insist you go first.

Eventually, someone will go first, and that person will make history.

One small sip for man, one giant GULP for mankind!
