Diana is a legend, an icon, a star.
Why a duck was chosen, we do not know. It has been suggested it is due to CUADC, when said as a word, sounds like "qua-duck". She is particularly precious to techies, who often require her as a shoulder (or a wing) to cry on during get-ins and get-outs.
In 2022 she had to undergo surgery after some damage cause by the 2021 Panto, Rapunzel. She now has several stitches in her neck and we wish her a speedy recovery.
