I have an air bubble stuck somewhere below a hunk of undigested hamburger and I seem to be unable to burp it up. This is not the worst of my problems right now, though.
Now, why did I write 'should' instead of 'must'? Well, if there's a person that knows what these things taste like it's obvious that person ate them. I don't recomend that you eat them but I'm not discouraging you either; it turned out fine for me.
