How I think that happened:
"Hey Jimbo!"
"What?"
"You remember if that axle is supposed to be four feet from the front or four feet from the back?"
"I don't remember George. Just get it done, we're almost out of beer."
"Well just let me weld it up real quick here and then we can go down to the store and get some more. Anyways, I'm pretty sure I got the axle in the right spot."
