Understanding how "Comedy" works

Look, maybe Krugthulu is right and the President can order a $1 Trillion Dollar Platinum Coin.  He probably is, he's got a Nobel Prize in Economics and I recently failed to be named "Blogger of the Year" or even one of many runners-up by my own self-funded internet publication (damn you, Skippy the Bush Kangaroo! and blog about collecting bottlecaps!).

But how can anybody think that the idea of a single, trillion dollar coin is somehow not a subject that lends itself to humor?

It may be tragically funny, but it is still funny.
