Alright, listen up, buttercup. This joke is playing on the word "female." See, the joke is that the letters "Fe" are the symbol for iron on the periodic table of elements. The joke writer is implying that women are superior to men because they are "iron men." And since you're reading this, I'm guessing you didn't know what "Fe" stood for. Sad.
