From a woman who was intently studying the free calendar she'd just received:
"Is that a cow?"
(peers closely at calendar page, holding it 6 inches from her face)
"I think it is. That's a COW!"
(looks around to realize that others are not sharing her wonder at correctly recognizing and identifying a member of the bovine species)
"Well, it's...it's hairy. I've just never seen a hairy cow before."
I really wanted to engage this lady in conversation at this point, but was stricken effectively speechless for so long that by the time I recovered, she was gone. I never got to find out how cows are upholstered on her planet.
