The Difference Between a Biscuit and a Cookie

We wanted to finish the year off by trying to squeeze in as many problems that we could solve as possible. We've got at maximum two minutes to try and solve each one. And then you're going to stop us when we run out of time. The first quick fire question is from Adam Batton on email and he asks, what exactly defines the difference between a biscuit and a cookie? Matt: There is nothing. Other than the fact that different people have different names for them. What if you went to Subway? That's definitely a cookie.
