"Eating E.T." is a mock alien barbecue, because... well, I really don't know.
Eating E.T. is a hands-on exploration of our intimate relations to other species, real and fictional. A life-size, gluten replica of E.T. The Extraterrestial, roasted whole on a spit and eaten together at festive social events, provokes discussions and questions on what is a stake in our practices of eating.
Oh. That explains... nothing, really.
