There was the one about the mayo. Basically a woman bought a taco bell chicken wrap effort but specifically asked for no mayo. As she was driving along she noticed that they had included mayo, but it didn't taste like regular mayo, so she she ate it all anyhows. Later on in her journey she had such bad pains in her stomach that she had to stop at the nearest hospital where she had really bad food poisoning or somesuch. Anyhows, it turns out that the chicken meat had a... damn, whats the word... basically like a big boil full of puss and stuff. But it was under the breadcrumbs/ batter/ whatever. Anyhows it had been overlooked when cooking it, and the "mayo" was actually all the puss and stuff inside it. Tops.
Again, thats just another urban legend. Still, put me off chicken from fast food shops for a while. Yuck.
Oh, and there is a Michael Moore type book around called something like fast food nation. I started reading a few chapters, but I had got past the McNugget bit (which I don't like anyhows) and had read on the back something like "You will never eat at a fast food joint again!", so I decided to stop, not buy it, and get out. After picking up a book called "Willing slaves" about how we work our ar*es off for no good reason. And I also wanted a burger from BK or Macey D's without feeling ill.
Cheers
(erm... for the chicken story...)
I am 99% probably lying in bed right now... so don't blame me for crappy typing
