Not everyone will understand at first listening, but while being a great and catchy medieval tavern style song, it's lyrics are also very meaningful: many men and women, desperately in search for "love", end up starting affairs with "monsters" (on the inside, more than aesthetically), and while they initially think they've found happiness, these monsters end up eating their entire lives, and it was their choice only to allow the monster to do so.
Don't be like the farmer.
