I overheard an amusing story about the Flash Strips Friday on my ORD->OAK flight as Feorlen and I were coming back from T-day festivities.
The person in the seat in front of me commented on how strong they were to the FA who was serving her. The FA giggled and related the story of an older passenger(she estimated 80+) who kept ringing and ringing the call button.
Every time she went up there, his request was the same. More water. She'd bring it to him, he'd slug it back and 30 seconds later she'd get *dinged* again. After a couple times of this she asked him what the problem
was.
It turns out he opened the package and popped the ENTIRE contents in his mouth

He had no idea what they were.
It kind of reminds me of the various "Green Tea" or "Guacamole" stories I've heard about peoples' initial encounters with Wasabi paste
