Anyway, one day, these brothers decided to go on a hiking trip. They all met at the crossroads, embraced as brothers do, and set off. One of them complained the whole time, but the other two had a great time. One of them forgot to wear sunscreen and he burnt, but the other two didn't. One of them had recently had surgery and so he had a little trouble maneuvering the trails, but the other two got along just fine.
Once they made it to the top of their mountain there was a waterfall. At its base there was a big beautiful clear reservoir from the falls. One of the brothers took a picture of it, but the other two forgot their cameras. One of them called his wife and told her about it, one of them still didn't have a wife, and the other one didn't get any reception.
The Moral: Three brothers hiked up a mountain and all three peed in the water. It's that simple.
