Duffy the Vampire Slayer

Very poor "comedy" sketch if you ask me. The BBC have been plugging this on the BBCiPlayer channel.

1. Why does Duffy look fat in the cartoon?
2. Why is there nothing more to this sketch other than a similarity between the names "Buffy" and "Duffy"?
3. Why now? Last year there was a point (when Duffy was lesser known) when it seemed every interviewer asked her about the vampires... but that jokes seems to have worn off by now so why is this sketch on now?
