Peter Miniutti's call for a name for the Coles delivery robot (C8) certainly demonstrates the wit of the readership. While Paul Johnstone of Bondi suggests "Coles Porter", Joy Cooksey of Harrington offers the slightly familiar "CoRo". Best of all, however, comes from Les Shearman of Darlington who came up with "Rob".

More on those schoolboy haircuts (C8). Brian Collins of Cronulla writes: "In the late '60s, when long hair was becoming fashionable, the principal at the school where I was working suspended two senior boys until they had a haircut. Later that evening I was having a drink with my brother-in-law and some of his former school mates and I related the story to them. They then started to reminisce how 10 years earlier, when short crew-cuts were the fashion, some of their mates had to wear a hat or were suspended until their hair grew. As the conversation went on we realised we were talking about the same person who was the principal on both occasions. There’s just no pleasing some people!"

"Alan Guihot's 'buy a new printer rather than a new cartridge' theory (C8) may be a false economy. New printers typically come with low-capacity 'starter' cartridges deliberately designed to run out quickly," says Alan Smith of Harristown (Qld).

"I dips me lid to Denis Minehan," says Stewart Smith of Tea Gardens. "He's been to Hell (C8) and back!" Going one better, Merilyn McClung of Forestville writes: "While on holiday in Tasmania we travelled from Hell's Gates to Paradise, in one day."

Continuing the discussion, Ken Arnold of Frenchs Forest says: "I note that no-one has mentioned the town of Hotazel in South Africa. So named because, well … it is."
