Three NASA football fans

An Arsenal fan, Chelsea fan, and a Liverpool fan, all working for NASA, were trying to figure out where to go on the next trip.

The Chelsea fan said, "We should go to Mars."
The Liverpool fan said, "We should go to the Moon."

The Chelsea fan and the Liverpool fan sat there arguing for a while. Suddenly, the Arsenal fan shouts, "Stop arguing! I know where the next expedition should be to... the Sun!"

The Chelsea fan and the Liverpool fan looked at each other and started laughing. The Chelsea fan finally said, "You can't go to the Sun. You would melt or burn up before you even got close!"

The Arsenal fan said, "Duh... not if you go at night!"
