There was a fortnight in 2013 when Betteridge's Law was the only thing anyone at my work talked about, and one of us printed something about it out. Printed. On paper. It was on the kitchen noticeboard for a year.

Sighting, 16 February, a driving instructor's Facebook page. Betteridge's Law, used correctly, in full, with no visible irony. Nobody involved is under fifty.
