Sprichwoerter/Proverbs

Have fun with random stupidity screenshot screenshot

Motivation
A German parlor game “Verrückte Sprichwörter” (“Crazy Proverbs”) turned out to be much more fun than its title let anticipate ...
I was eager to use the idea to create “random proverbs” in a little fun project.
Okay.., the output of this program is not guaranteed to be funny as computers are too dumb to understand humour while the original game engages the players' own intelligence.
Requirements
Linux
The gem can be installed on Windows®, but I do not know if it works on that operating system. Also, I do not care to know.
A recent Ruby interpreter.
Functionality
The program comes in two versions (both included in the gem): proverbs creates new proverbs in English, sprichwoerter does the same in German.screenshot Call with the argument '-h' to see the options in each language.
