These are bludgeons. Where is the subtlety? Where is the possibility that these might actually be true? If there is just blatant "Ha Ha. Look at this obvious falsehood we're pushing. Aren't we funny?", then there is no surprise catch. There is no, "Damn. What if they're serious?"
I'd like to think of this figurine as just a really good April Fools joke.
An example of what I'm talking about in terms of good jokes would be Perl and Python Announce Joint Development on the next generation of the two languages, Parrot. This was actually a good enough spoof that Simon Cozens actually need to post an explanation of how Parrot came about and that it was an elaborate hoax. Best of all, it actually took on a life of its own and has become actuality instead of a spoof. See here, here, and here.
I don't expect all jokes to work that well but at least a little of bit 'catch my breath for a moment' would be nice.
