Yes, usually they don't do anything, but it seems as if they can do a lot more than we think.
A friend of mine worked as a missionary somewhere in South Africa.
Because it didn't rain for many weeks his competition decided to organise a rain dance next evening and my friend also went there to see what's going on.
After a pretty long time dancing, singing and doing whatever was necessary on a forest glade, there came a very big, highly erected holy black mamba out of the forest, went through the crowd that opened a gab for the snake, and disappeared into the wood at the opposite side of the place.
Immediatly afterwards it started to rain heavily.
Back at home my friend sorted his stuff, cancelled the job and came back to Germany.
