Fridge Brilliancenote Examples are organized in order of the episode in which they can first be detected.
Anthony Kiedis, dressed as Kurt Cobain, sings the lines "it only hurts when I laugh/gone too fast" in the Dani California video. The significance of that just hit me. For some bonus symbolism, one of the candles in the foreground blows out and the camera lingers on a shot of the smoke rising up.
Due to Kiedis's unique style of writing, a lot of their lyrics rely on this. An example would "What could be wetter than an English girl...?" in "Emit Remmus" having a double meaning, also referring to how rainy it is in England as well as the sex between the aforementioned English girl and American man.
