Thanks for that addition, tsuwm....I had been wondering if it had anything to do with the fact that some peoples do, in fact, eat grubs. Got to wondering about the whole thing when I borrowed Michael Palin's Full Circle videos from the liberry and at one point, he was eating grubs in an Asian restaurant, and of course took the opportunity to pun a little - after a mouthful he said, "Well, it's not the best [whatever type of grub it was - can't remember name] I've ever tasted, but it's still good grub...."

I tried witchetty grub in Australia once. You can eat 'em raw or cooked and I had a "fillet" of the cooked (our guide cut it up into slices so we could all have a taste). Very nice, actually - kind of a nutty egg flavour. Definitely good grub.
