There's something deliciously funny about dirty jokes, right? Growing up, sexual jokes were the obvious choice for everyone and even after growing up, they're the ones that crack us up the most. There are strong parallels between the Germanic portrayals. But for some others, funny and naughty work like the perfect combination. Twin incest is a prominent feature in ancient Germanic mythology, and its modern manifestations, such as the relationship between Siegmund and Sieglinde in Richard Wagner s Die Walküre, and a feature in some Greek mythology, such as the story of Byblis and Kaunos. And for some, it's something that's so in-your-face funny, you can't help but laugh out loud. For some, it's a matter-of-fact thing said with a hint of sarcasm.
