There was a certain joke that circled throughout the culture of the evaniels for thousands of years; a joke that most probably every men, women, child, and even old people that could barely run anymore still know.
The joke goes like this,
'There once was a farmer named Valasmir who circled an entire planet to search for his shovel. But it turns out, he was holding it all along.'
That was it. That was the joke.
Most of the other races couldn't really understand how that was a joke, or how it could even be funny in the first place. But for evaniels, it held a meaning that only they could understand even if it was the first time they heard it.
The evaniels tell it all the time to the other races; but each time, they have to explain what it meant. The weirdest part of this was— that the joke was intended to be told to foreigners.
