A woman holding a baby walks into the chemist shop in the main street of Goolwa and asks the shop assistant whether she can use the shop’s baby scales.
The assistant says: “Oh, sorry madam, but our scales are not working. However, what we have been doing today is weigh the mother with her baby on the adult scales, then weigh the mother by herself, and take that weight away from the first weight to find out how much the baby weighs.”
And the woman says: “Oh no, that won’t work.”
The shop assistant says: “Why not?”
And the woman says: “I’m the baby’s auntie.”
