Lighthouse keeper

At low tide, the lighthouse keeper could walk from the lighthouse to the shore in order to pick up supplies. At high tide, the lighthouse was completely isolated from the shore.
Insulated cables carried power to the spotlight and the lighthouse keeper’s cabin.
The toilet emptied directly into the sea.
When he was drunk, the lighthouse keeper enjoyed climbing up the stairs to the spotlight and pissing over the rail into the sea.
This wasn’t a problem when the skies were clear and the winds were calm. However, when there was a storm, he always regretted pissing into the wind.
