One day, three men were hiking and unexpectedly came upon a large, raging, violent river.
They needed to get to the other side, but had no idea of how to do so.
The first man prayed to Woden, saying, “Please Woden, give me the strength to cross this river.”
Woden gave him big arms and strong legs, and he was able to swim across the river in about two hours,
after almost drowning a couple of times.
Seeing this, the second man prayed to Thor, saying, “Please Thunor, give me the strength….. and the tools to cross this river.”
Thunor gave him a rowboat and he was able to row across the river in about an hour,
after almost capsizing the boat a couple of times.
The third man had seen how this worked out for the other two, so he prayed to Frige saying,
“Please Frige, give me the strength and the tools… and the intelligence… to cross this river.”
Frige turned him into a woman. She looked at the map, hiked upstream a couple of hundred yards, then walked across the bridge.
