One of the most useful tools to have around. I love inventions that are simple, yet they serve many purpose to make everyday life a little easier. What/how I use(d) my bungees...

Holds down the stainless cooler in SUV
Keeps shade structure intact at Burning Man.
Holds multiple the sleeping bags together
Holds down car trunk door for large items.
Keeps the temporary shower caddy steady.
Bundles my firewood for easy transport.
Stabilize fragile items during drive.
Extra lock mechanism for storage bins.
Moveable hanger for garden hose.
Moved large bamboo on top of car.
Bands long cables (smaller bungees).
A temporary clothesline inside my tent.
A temporary clothesline outside my tent (tree to tree).
Held up my neighbor's tree to our fence.
Tied down giant ice block to bicycle.
Dog chew toy (not by choice).

Once, I got mad at my boyfriend for doing physical work, as he has a bad back. I bungeed him down to a lawn chair.
