I received this forward:
What probably happened is, the water the lettuce was washed in contained polliwogs (mature tadpoles) and these became fresh new frogs, right in the packages. E-Coli isn't the only thing in bags of lettuce/salads. :X

I don't know if this was photoshopped into the picture or not or whatnot, but I find it incredibly disturbing to think that something like this could potentially happen. UGH. I can't imagine that there would be much air inside for them to breathe inside the packaging but.. YUCK. DISTURBING to think about.
