I don't get why people are grossed out by "strange" foods. I find the idea of eating (live or dead) crickets appetizing. I have eaten cow tongue, ox tail, lamb eye, and live snails. I mean, sausages should be (assuming you're eating actual sausage) pig intestines stuffed with meat, so I don't really see the problem. That sounds even more gross than eating a tongue.
And, I have already eaten "moving" food, to answer your question.
(also, if you haven't tried it yet, try cow tongue tacos. You can probably get them at your local family-owned Mexican restaurant)
