I love the way language is always changing - morphing, developing, growing. Sometimes the way it changes turns the meaning of a word or phrase on its head.
Having noted this from Jane Austen's Mansfied Park a few months back:
"If Fanny would be more regular in her exercise, she would not be knocked up so soon."
I was childishly delighted to come across the following from Emma (p.52) recently:
"where young ladies for enormous pay might be screwed out of health and into vanity..."
No further comment needed. My apologies to Ms Austen.
And, yep, I like toilet humour too.
