cf. Flight of the Bumblebee :
Whatever its origins, the story has had remarkable staying power, and the myth persists that science says a bumblebee can't fly. Indeed, this myth has taken on a new life of its own as a piece of "urban folklore" on the Internet.
This means the scientists who supposedly determined it couldn’t fly were wrong, of course. But the scientists at least were sincere about it.
It’s not respecting an audience of students or anybody else to address them with fallacies, however more colorful than a bland “historically, a third of our entrants have graduated.”
