A friend of mine recently bought some tobacco-free "tobacco" for a hookah pipe. Eager to convince me that there was nothing unhealthy about it, she grabbed the box and read out the ingredients.
The stuff was produced in India, so I think someone had a little fun when they were asked to translate the ingredient list into English.
On the other end of the scale, I have a necklace that came with a tag which proclaimed (alongside pictures of choking people)
Caution: Necklace is not edible
Warning: Do not eat
THIS NECKLACE HAS NO NUTRITIONAL VALUE
Oh, yes... does anyone else read labels just for the fun of it?
