when younger my granddaughter and I were waiting at the bus stop and as the bus approached she said nan it's a dibble docker we all still call double deckers that now lol
A neighbour didn't spoonerise but often used the wrong words. He was telling me about a mutual friend and said you'd think a man of his calipers (calibre) would know better.
At the arcade where I work, a regular had a large win. She was asked 'Why don't you leave now while you're ahead?' She replied 'That's not my velocity.' :)
