The Third Head
It has become abundantly clear that there is no children’s show that is completely devoid of double entendres. That isn’t inherently a terrible thing, though it’s something to consider. A kid won’t be harmed by a concealed joke; they’ll just be bewildered, but adults will have a good time laughing at it.
The Flintstones was one of our favorite shows when we were younger. However, when we first watched this scene, we had no idea why Fred and Barney were laughing too heartily at a third-head joke. However, we didn’t think about why an additional head would make Barney have three altogether. Where is the second one?
