Scientists recently decoded the first message from an alien civilization...
It read as follows: Simply send 6 x 10^50 atoms of hydrogen to the star system at the top of the list, cross off that star system, then put your star system at the bottom of the list and send it to 100 other star systems. Within one-tenth of a galactic rotation you will receive enough hydrogen to power your civilization until entropy reaches its maximum! IT REALLY WORKS!
(if you don't get this one, don't write me and ask me to explain it to you ...)
