This reminds me of something similar to somebody walking up to their neighbors house with a box and when they knock telling them that it a box full of defused WW2 explosives and saying they want to share it. Does it matter? Or, here's another good one, you get some people to rent your house for a month, and you tell them to watch out, they have dogs, and the renters reply, "Oh no, don't worry, none of us are allergic!"
Whats the harm? It's like shooting someone with a squirtgun. Ow.
