fwh,

I'd keep talking. Although I hate to stigmatize illnesses, I wouldn't mind having a bit of fun with the TSA.

"I always get the outbreaks when I travel. You know how it is.. the sores are just everywhere. At least it's only contagious from skin-to-skin contact. I can tell by your face that 'you've been there; you understand. One day they'll have a cure for people like you and me. Sometimes I get this discharge, and I'm thinking it's more than 3.4 ounces. DO I need to declare that separately? Here... let me show you; I have it saved for you in my bag..."

It's kind of like at SFO, when they were obsessed with upper-body friskings of "random" passengers at the metal detectors. It was easiest to just pick the line with the TSA employee of the opposite gender. But if that didn't happen, I would always start sneezing and grab a Kleenex. Then look up, roll my eyes, and make some comment like, "I just can't shake this cold." Worked like a charm every time.
