I was prepping the turkey this year (we get ours from a farm), and my wife was sort of half watching.  I was cleaning out the cavity and saving the guts (I like 'em cooked with butter, garlic, Tobasco, and cajun spices - and nobody else will eat them), and I pulled out one my wife had not seen.  My wife was looking at this innard and said it looked strange and asked if I was going to eat it; I said no because I'm not fond of eating lungs.  She immediately turned white, stood there for a few seconds, and then turned and left making gagging noises.
She understands that food does not magically appear on foam trays, but I did get a bit of a chuckle out of it, especially given the recent Palin footage showing the turkey 'guillotine' in use.
I don't subscribe to the 'they were put here for us' notion, but I do have to wonder sometimes where people think their food comes from.  Though I think it is probably better if the alchemy that produces Twinkies is a stone left unturned.
