This pretty vine grows in my backyard, up the fence. A few times a year I pull up as much as I can and give it to the goats. They love the vine and the little one-inch-long fruits.

It's known as creeping cucumber, cuca-melon, and mouse cucumber; its botanical name is melothria pendula.

The fruits are supposed to be edible by humans when they are green, but not when they are black/ripe. Some say they taste just like or even better than a cucumber, others say it's like a cross between a melon and a cucumber.
