These are called provocative questions. The reasoning is that they don't care so much what answer you give but they are watching how you respond to the question. The key is to appear mostly unflappable and demonstrate the ability to give short, logical responses to seemingly off-the-wall questions. Pause briefly after each question to compose your response and give the impression of gravitas. Then give a high level summary response. Just don't ramble and don't give inappropriate responses. Treat the wacky questions as though they are no different than "Tell me about your best experience obtaining a sale by adding value to the customer" and you'll do fine.
