And, before you ask, a 'puppy post' is referring to a TSA-feel good (or so they think) post generally started on a Friday afternoon as a way to distract the Kettle's from the multitude of repeatedly asked, & repeatedly ignored, real questions posed. (Remember, PV was supposed to be a forum for 'dialogue' w/the traveling public over serious issues & concerns ).

And yes, the term was coined because of a real puppy post made on a Friday afternoon...
