There are a number of viral vids on YouTube that follow equivalent "hoist by his own petard" themes, or which in other words, would never have become so popular if the individual being collectively mocked had quietly gone upon their own way instead of causing a scene.

They represent an interesting phenomenon in the internet age, a kind of 'folk' punishment by ridicule and generating general discomfort somewhat akin to the custom of 'rough music'*: http://en.wikipedia.org/wiki/Rough_music

"Rough music, also known as ran-tan or ran-tanning, is an English folk custom, a practice in which a humiliating and loud public punishment is inflicted upon one or more people who have violated the standards of the rest of the community. [...] Noisy, masked processions were held outside the home of the supposed wrongdoer, involving the cacophonous rattling of bones and cleavers, the ringing of bells, hooting, blowing bull's horns, the banging of frying pans, saucepans, kettles, or other kitchen or barn implements with the intention of creating long-lasting embarrassment to the alleged perpetrator.[3] During a rough music performance, the victim could be displayed upon a pole or donkey (in person or as an effigy), their "crimes" becoming the subject of mime, theatrical performances or recitatives, along with a litany of obscenities and insults."

I see there's even a dubsteb version of the Bath Roadrage incident now: Dubstep Bath

Here's another well travelled example, which is arguably more funny for the bizarre inclusion of blokes in drag and spiderman: http://www.youtube.com/watch?v=-yvU6sifwkI
