Mmmm spam........
I was actually going to spam earlier but then realised there were mods in this forum. Not like ancient history, spamming heaven.
Anyways, silver nitrate smileys are ok. All they do is stain the skin and you'd be left with happy faces all over your body. Happy = good.
On the other hand, if they were sad "smileys" or were evil satanic messages/symbols, then the earth would open up and and you would be crushed into a puny pancake faster than barium sulfate precipitates. Your bodily fluids will diffuse out and you would be as screwed as someone who had just swallowed concentrated sulfuric acid.
So my friend, the safest thing is to just stick with spam ham (or spurkey even). So much more funnerer!
