We have an indigenous weed known as a "Bathurst Burr". The plant is like a small green shrub with sharp needle points (about 1" long) to protect the burr. Two or three of this ova shapes are about the size of a garden pea. They have hooks rather like those of "velcro" (maybe that is where that product had its origins). Pre noon we'd play our jokes but afternoon translated to "pig-tail day". We'd get strips of cloth, attach a burr to one end and then try to secretly attach it to the back of someone. The joke worked two ways, being caught trying or not realising that you had been tagged.
In Australian TV infancy a news service carried a story of how the national phone provider ran some people with the view to clear dust from their telephone lines. The customer was instructed to place the handset in a paperbag and wait for a few minutes whilst the technician blew compressed air down the line to remove debris.
Whilst on this subject, yet to check, quite some years back the BBC had a documentary relating to the growing and harvesting of spaghetti in Switzerland (?). I don't think that was related to April 1.
Oh, LRM, let us not sacrifice fishes needlessly today!
