The Doctor: This whole world is swimming in WiFi. We're living in a WiFi soup. Suppose something got inside it. Suppose there was something living in the WiFi, harvesting human minds. Extracting them. Imagine that. Human souls trapped like flies in the world-wide web. Stuck forever, crying out for help.

Clara: Isn't that basically Twitter?
