He didnt know Yoda but I suspect that was my fault since I was not to pick a specific object… But he did guess Goblin, so close enough I’d say… 
You failed miserable to get one post Oh Evil one.
Yesssssssssssssssssssssssssssss failed to get even one. Untill this one obviously.
Damn it got Wormhole in 19 Questions.
Yay. It failed to get a can of Fizzy drink in 30 questions.
I chose cat…which if you are not specific can mean tiger, lion, house cat, etc. He stopped after 26 questions…he guessed Mammoth (question 23), Donkey (#25), and Brontosaurus (#26). Vader needs to work on his powers…
Oh my god no way…he got “eyeball”??? I didn’t keep track, something around 20 or so…Ok-let’s get down and dirty—“Spock”…
Got him! 30. But then he asks a group of Q’s and one of them was “disease”. To be honest I wasn’t sure how to answer some of the Q’s…
“spoiled meat”
This is a pretty good one. It managed to get tobacco, coffee, but couldn’t get candy bar wrapper.
I decided to try “penis” (my humor is not juvenile!) and he began by asking if it was big and black. But then he got way off track…
I have used my jedi-powers to persuade the machine to give me the passkey.
