"How's things."
You are right. It SHOULD be "
How ARE things?".... How IS one thing, How ARE more-than-one thing...
BUT,
everyone says, "How's things?" Wrong, but what people say.
"How's things?"
"Oh, things are okay."
"Aren't it funny"
I have never heard "Aren't". I think you heard:
"Ain't it funny."
"Ain't" is horrible, 100% wrong, but it is used. It means, 'is not', 'are not', 'am not', 'have not' and 'has not.' It is used any time the speaker wants to sound... very forceful.
Son: "I am going to go to the dance."
Father: "Son, you
ain't going to the dance (
you are not going...) and also, you
ain't taking the car and you
ain't going to see your friends. Your friends, they
ain't smart, like me."
Awful word, but used sometimes.
