Rain

Imagine going to the beach, seeing the sea and some dark clouds... A little rain starts... And all of a sudden it rains like crazy! You get wet all over in under 5 seconds! All you can do is grab your stuff and run under the next tree and feel lucky that you just have your bathing clothes on... And that goes 3 times and after it the sun comes out a bit and all day there is no more rain... Really fascinating! Even if it sounds harsh it was a experience that I will never forget... No need for a shower, just go outside :D
