Growing up in Australia I was used to hearing weather alerts.
One that has been with me for about 35 years (I feel so embarrassed that I didnt get corrected years ago) is where the weather man says:
"There is a sheet weather alert"
Now I thought it meant that the rain was so hard, it's coming down 'in sheets'.
My mum nearly pee'd herself laughing when I recently told her this one.
It's actually a "sheep weather alert" for the farmers.
