Very good Bee Gee. What does a vegetarian cannibal eat?
Well, cannibals don't just eat their own species. In fact, I'm fairly certain that they eat a lot of other things and add spices and vegies to their "meals".
And, vegetarians (believe it or not) don't just eat vegies, either. Microscopic animals inhabit many of the vegies that we eat (yuck!), so ingesting vegies really means ingesting a little "meat" in addition to vegies. Also, humans can not survive without the symbiotic affect of microscopic "animals" in their digestive tract. How did those little animals get there in the first place? They were ingested. Thus, every vegetarians' very survival depends upon the fact that s/he has "eaten" animals.
Therefore, neither "vegetarian" nor "cannibal" are religiously, scientifically, or rigorously exclusive categories or behaviors.
I am guessing that a vegetarian cannibal eats pretty much the same things the rest of us do. Meanwhile, s/he espouses a lifestyle that proclaims distaste for carnivorous diets, yet espouses cannibalism.
Or, is this one of those riddles that has a sick "silly pun" as an answer? Something like: "the fruits of her labors" <img src="/ubbthreads/images/graemlins/suspicion.gif" alt="" /> <img src="/ubbthreads/images/graemlins/down.gif" alt="" />
I hope not.
