From the originating website:The Doo-Dah News Network brings you the finest headlines that you can sing to the tune of "Camptown Races" if you add "Doo-Dah" to the end.
As near as I can tell, it works - feed any of these into Google and you'll come up with a genuine news story. What I'm most curious about, though, is how it determines the number of syllables in any given headline, or how it decides where to truncate a headline in order to fit the seven-syllable criterion.
All that said - it's so awesome in such a totally pointless way that truly, this must be what the Internet was invented for.
