If only they were real headlines published in real news media as opposed to being written by writers of the Tonight Show, or the David Letterman Show, or the Daily Show with Jon Stewart, or some other aspiring comedy writers...
For me, 100% of the comedy depends on the issue of were they ever published or are they just the invention of some wanna be writers somewhere..
On Monday nights Jay Leno (NBC) has real world funny "Headlines" in which he gives the source so anyone can check it. THAT'S funny!
Tony, those ARE real headlines or at least very similar. I regularly see headlines which are to say the least open for multiple interpretations.
Saddest about them is that the editors writing the headlines don't have a clue that they're writing something ambiguous, thinking they're just being cleverly writing a short succinct description of the topic.
