I think erwict is absolutely correct....it sneaks in....that stuff they call cheese is really glue anyway so don't bother trying to scrape it off erwict.

what's really happening is that every glue burger you eat sticks to the side of your intestines....eventually they will be blocked off and you will die....the stuff hardens inside too.

It' a huge murder plot....they do speak english erwict, they just pretend they don't so they can make sure to get the glue on your burger.
