Also, amusingly enough, it features a spherical Earth. And I have to wonder how they'll fit "one couple of every species of the Earth" in that ship, huge though it is, without involving Gallifreyan technology.

Biblically speaking, it's seven breeding couples of every "clean" species, one of every unclean.

What's much more nonsensical than fitting all those animals onto the ark in the first place though, is the idea that it would actually save them. You've got predators reduced to equal numbers with their prey species; memory check, what do they live on?
