It's the crossover of dreams. If Star Trek is the classic and definitive American Sci-Fi television series, then Doctor Who is that of the United Kingdom. As a fan of both, how could you not want to see the series mashed together?

While the concept might not seem like it makes sense in terms of either of the series' canon, I'm sure that between all the technobabble and wibbly-wobbly-timey-wimey stuff, they have found an acceptable way to bridge the two universes.

In this case, it appears that the Eleventh Doctor (of the current series, played by Matt Smith), will be joining the crew of The Next Generation, along with his faithful companions, Amy Pond and Rory Williams. Why, you ask?
