Isn’t “field day” an odd term?
It comes from the military and refers to a day of exercises where soldiers got to show their stuff, as well as being put through their paces.
Ever since I learnt this, whenever I hear it applied to journalists or politicians, I’ve had this image of journos and pollies running around in a field. ‘Tis amusing.
(Incidentally, “put through their paces” comes from the world of horses and relates to testing their performance walking, trotting etc. You know, just in case you were wondering.)
