The largest-ever recorded irony quake occurred in Pittsburgh in 1975, when a national bus drivers' conference had to be cancelled because the coaches arranged to transport the 450 delegates to the conference hall didn't show up.
The resultant quake measured 9.3 on the Chinstroke scale, and killed nearly 3000 civilians in a vast array of deeply ironic death scenarios. The shockwaves could be felt up to 250 miles away, resulting in thousands of scattered ironic incidents such as firemen getting stuck up trees and having to be rescued by plucky cats.
Steamroller operator Chris Positionmaster-Hercock, who was near the epicentre of the quake (and narrowly escaped being flattened by a huge metal pipe rolling down a hill), described the scene as 'horrifyingly devastating and very very funny'.
