Looks like the ThudGuard has some Australian competition, at least in the product naming department. The "HEAD BUMPA˘ [tm of course, because you wouldn't want to see a whole bunch of counterfeit Head Bumpas for sale on Canal St] is more of a foam harness than a helmet, closer in design to the original Puddin'heads of old, when the governess would just wrap a towel around a kid's head and be done with it.
The "HEAD BUMPA˘ is not just for Australians, though, it "is distributed worldwide through normal postal methods."
Which makes me wonder, now that the kids are protected worldwide, why don't we see more baby cagematches:
Now if you'll excuse me, I gotta go make some calls.
[Update: Um, yes, I just realized you could probably do a shot-for-shot remake of Mad Max in New Orleans right now and call it Beyond Superdome, and it would be supremely unfunny. In fact, it's getting less and less funny as I type this.]
