Yep, Weird Al is still going strong.
Do you mean "novelty" as in parodies of real songs, or as in odd little tracks that most "artists" wouldn't be caught dead releasing because of subject matter or arrangement?
If it's the latter, I'd consider "Barbie Girl" by Aqua a "novelty" song that was a big hit a few years ago. Also Lou Bega's "Mambo No. 5."
There's usually quite a few "novelty" tracks in the UK over the course of a year. "Fast Food Song" by the Fast Food Rockers was just a #2 hit a few months ago....
