The History Episode (and season finale). Where else could you find out about the maths of the Census, discover Aristotle's lesser-known brother Bob, learn about the shortest man in history (spoiler: only because of a mathematical error), and be caught out by an excellent puzzle about the Emperor Claudius?

Not to mention a terrific interview with famous archeologist Sue Greaney, in which we learn some extraordinary mathematical facts about Stonehenge!
