A “clickbait” version of the popular lightbulb joke is:
       
“How many clickbait articles does it take to change a lightbulb? The answer will shock you!”
   
The joke is a pun; the answer will “shock you” (surprise you), but might literally shock you (because it involves a lightbulb). “How many clickbait articles does it take to change a lightbulb? The answer may shock you” was posted on Twitter by Saul on December 8, 2016, and on Reddit—Jokes on December 12, 2016.
   
     
Wikipedia: Clickbait
Clickbait, a form of false advertisement, uses hyperlink text or a thumbnail link that is designed to attract attention and to entice users to follow that link and read, view, or listen to the linked piece of online content, with a defining characteristic of being deceptive, typically sensationalized or misleading. A “teaser” aims to exploit the “curiosity gap”, providing just enough information to make readers of news websites curious, but not enough to satisfy their curiosity without clicking through to the linked content. Click-bait headlines add an element of dishonesty, using enticements that do not accurately reflect the content being delivered. The “-bait” part of the term makes an analogy with fishing, where a hook is disguised by an enticement (bait), presenting the impression to the fish that it is a desirable thing to swallow.
