The Setting: Someplace ancient, you know with like togas and columns and stuff. A father and son prepare to leave their humble ancient-style home.
Father: Alright son, before we head out you need to put your sandals on.
Son: Why?
Father: Well, we’re living in this ancient-style world and we don’t have paved roads and even then paved roads wouldn’t be very comfortable unless it was paved really recently.
Son: Why?
Father: Well, because little bits of pavement break apart after time and so those can stick into your feet and hurt.
Son: Why?
Father: Well, I guess it’s just a matter of pointy things hurting skin in general.
Son: Why?
Father: Well, because that just seems to be the broader way of looking at the question.
Son: Why?
Father: Well, because first we were looking at something that was an isolated instance of a pointy thing hurting skin and so to explain that I tried to use a more general example.
Son: Why?
Father: Well, it was really just the first thing that popped into my head as a means of explaining it.
Son: Why?
Father: Well, I guess. Wait a minute son, I think you’ve stumbled on something here. This incredibly annoying little habit of yours could be turned into a whole department at colleges everywhere and classes in these departments won’t ever really accomplish anything because at some point everybody needs to accept “Just because” or “Well, that’s just the way it is” and leave it at that. But that never happens in these classes. And the people who major in this department of study will go to parties with normal people who just want to have fun and make jokes and stuff and they will totally kill the mood and try to make everything all deep.
Son: Why?
ZAP! (a lightning bolt hits the child)
Father: Dear God, why?
Zeus, or Other Ancient God-Like Figure: Well, that child was obviously incredibly annoying.
Father: Yes, but why?
Z,oOAG-LF: Well, everyone’s time comes eventually.
Father: Oh why?
Z,oOAG-LF: Well, just because. Darn it.
