OK this is addicting and freaky. I've tried it 4 times. The first was a 'ladder'--it guessed it after 28 questions. The second was a 'hammer' and it guessed after 20. The third was a 'picture frame' and it guessed again after 20. The fourth was an 'ottoman' and it guessed it after 28. This is amazing! I'm going to try to stump it.
edited to add: I stumped it with "checkbook" ha ha!!!! Now maybe I can go to bed.
