I noticed one of the supermarket stores is experimenting with replacing round cans with square ones, the idea being they can stack more in a given shelf space.
It would certainly have brought an additional smile to the late Michael Bentine's naturally funny face.
There must be many who remember his zany TV comedy series It's A Square World.
More seriously, all the cans have ring-pull tops. Sometimes, they break off.
Could this be another brilliant marketing ploy - to make us buy a can-opener which cuts round corners?
