Seeing Doctor Who in a cartoon form is a gift enough for its audience but seeing them in the form of popular cartoon series, Adventure Time, would be all kinds of amazing. The animated show itself seems as though the writer and the production team were on some sort of hallucinogenic drug when coming up with the concept so it does mess with the head a little. It may seem like a kid's show but it has a lot of mature humour, too - exactly like Doctor Who itself. So this crossover would be extremely interesting to view. On the other hand, the reason this crossover won't happen is because the animated show isn't everyone's cup of tea and it probably wouldn't spark much of an interest. People are always wrong about something.
