Why would someone buy a way out-of-the-money call option that's expiring soon?
The most likely explanation is that the calls are being bought as a part of a spread trade.  It doesn't have to be a super complex trade with a bunch of buys or sells. In fact, I bought a far out of the money option this morning in YHOO as a part of a simple vertical spread.  Like you said, it wouldn't make sense and wouldn't be worth it to buy that option by itself.
