I think it all started when Han Solo said he could make the Kessel run in less than 12 parsecs. A whole panoply of morons let that one get on the screen.
I remember that, but haven’t thought about it in a light year. /s
It goes back to the Scarecrow in Wizard of Oz, after he got his diploma. “The sum of the
square roots of any two sides of an isosceles triangle is equal to the square root of the
remaining side.” Ha. Say it fast enough, and you look smart!
I was 8 when it came out. I didn't know a parsec from a parsnip. However, when I watched it after growing up, yeah, it stood out.
Given the nature of the “Kessel Run,” it actually makes sense. However, I’ve no doubt that’s an Expanded Universe alteration in order to save Lucas from himself.
