Unfortunatly, no one won the last round. However, Munkiman's Rogue Gallery one was hilarious (at least to me).

Answer: A bus driver was told to bring 20 psychiatric patients to a mental hospital. On the way there he stopped to buy a newspaper, and when he went back to the bus, all his passengers had gone. So, he drove up to several bus stops, collected the first 20 people he could find, and delivered them to the hospital, where he warned the staff that they would all cause trouble and claim to be sane.

Rules:

1. Don't share answers with each other, even answers you know aren't right. Doing so will get you disqualified for that round. This also applies for stealing another person's answer when you didn't come up with it yourself.
2. You may, however, share theories. If you come up with an answer with the help of another contestant, make sure you mention that you did so, and who that was so I can give them credit.
3. Each round, I will post the clues that correspond with that puzzle in a spoiler tag, assuming there are clues. Yes, there are some with no clues. Deal with it.
4. If you have heard some of these puzzles before (Rockhound and Robo, I'm looking at you), out of courtasy to the other contestants please don't share the answer to others.
5. There are no prizes for winning, save bragging rights.
6. If you believe you have the answer, post it in spoilers in the comments. Share theories through IM, PM, whatever floats your boat.
7. You will have one week from the posting of the new puzzle to solve it. Afterwards, the blog entry will be locked.

Go!
