The MD-80 has a very distinct crease where its two lobes join.

The two lobes are joined by the floor panels.  The design of the upper
lobe allows for maximum fuselage diameter at the PAX elbows.  While this
was good for the passengers, it did result in a very labor intensive
manufacturing process.

I believe one of the significant benifits to Douglas on the MD-95 is that
it IS a circular cross section, allowing automated manufacturing processes.
(The DC-9/MD-8x family were all assembled by hand.  Manufacturing labor
was, in general, in excess of 60,000 hours per aircraft - but I don't know
how much of that was directly attributable to the fuselage assembly process
