Dale Irby photographed every year since 1973. See SWNS story SWTEACHER: A teacher has become an Internet sensation after school photos of him wearing the same tank top and shirt for 40 YEARS went viral. Dale Irby, 63, accidentally wore the same brown v-necked tank top and big-collared disco shirt for two consecutive school photos from 1973. When he realised what he had done, wife Cathy dared him to repeat it for the third-year running. The PE teacher kept up the joke and for the past 40 years staff and pupils have eagerly awaited Mr Irbys arrival at school for the annual photo.
