Named to honor the two fine pilots from Northwest Airlines and there little "in flight snooze"
"Dude, I was so tired yesterday afternoon, I took a Northwest Nap. My girl called me 15 times and I didn't hear a thing"

Last night the old train station burned down while the cops parked down the block from it were taking a Northwest Nap.
