I'd like to propose an extension to Betteridge's Law. "Any headline that ends in a question mark can be answered by the word no." https://en.wikipedia.org/wiki/Betteridge%27s_law_of_headlines 

"Any headline that contains 'could' can be answered by the words, Probably not."

eg "This $500 bamboo bicycle could be a key to reliable, affordable, and sustainable transportation". Hmmm!?! Probably not.
