Cartoonist Kate Beaton — who helms the webcomic Hark, a Vagrant and once wrote the adventures of Sexy Batman — has never watched Doctor Who, but that didn't stop her from writing her own Who comic. In her adventure, "the Doctor with hair like this" and "hot sidekick assistant" "go back in time and solve a thing."
I'm committed to the belief that you can't properly parody something unless you have an intimate understanding of it — which is why I'm not sure what the point of this is. It isn't really funny, and it doesn't have anything particularly insightful to say about Doctor Who. (It can't, since by the author's own admission, she's never seen Doctor Who.)
