Did you know that you can fly in Titan by flapping your (winged) arms?

Next time you go to Titan—one of Saturn's moons—remember this cool factoid: "The atmosphere is so thick and the gravity so low that humans could fly through it by flapping 'wings' attached to their arms" as pointed out in Robert Zubrin's Entering Space: Creating a Spacefaring Civilization. How awesome would that be?
