So you know how Robbie, the emo teen from Gravity Falls turned out to have super cheerful parents? Well, it was also revealed that his parents are both funeral directors.
Gallows humor is humor about very unpleasant, serious, or painful circumstances. Any humor that treats serious matters, such as death, war, disease, crime, etc., in a light, silly or satirical fashion is considered gallows humor. Gallows humor has been described as a witticism in response to a hopeless situation. It arises from stressful, traumatic, or life-threatening situations, often in circumstances such that death is perceived as impending and unavoidable. -Wikipedia
