I was thinking of an F-16 and it guessed jet fighter, but since it wasn't an animal, and had wings and wheels, it probably wasn't too hard to guess. Then I thought of sunglasses and it guessed "CD case". A lot depends on how you answer questions that really don't have a good answer available. Like for sunglasses.."Would you find it on a desk?" Well, maybe, but not necessarily. Mine are right in front of me now on my desk, so it's possible.
Still, an amusing trick.
