Smell tester? What's he attempting to detect, foul odors? I mean, if he's quality control then what is he looking for? And people wonder where the gov't cheese goes, eh?
NASA Comptroller: "Well, we're just about ready to install the zero gravity toilet seat.. It's been put through a battery of tests, it's been super heated and super cooled to insure rigidity in any condition, it's been upfitted with zero-G seat covers to protect the astronauts from foreign contaminants, even the seat covers have been thoroughly tested to insure proper cheek sweat wicking.. Just one last, all important test to perform.. The smell test."

Engineer #1: "Well hells bells, boys.. Back to the drawing board then.."
Engineer #2: "Man, that one showed promise too... darn that George!" (jumps as George growls from within his cage)
