I'd like to remind you at four in the morning,
My world is very still

You get up every morning
From your alarm clock's warning

Takin' care of business

Goodbye, hard life

Takin' care of business

ok,ok we will let it ride already.

Let's see, they say it four times in each chorus, then repeat it ad infinitum at the end (which once prompted me to ask a friend, 'Hey, what was the name of that bto song they just played?'). No wonder I once heard them called Bathroom Toilet Overflush.

He's saying that the girls are trying but not succeeding at looking pretty.

I know that they at least USED TO teach in school that "ain't" is not a grammatically correct word. Its use has increased nonetheless. But even if it has been gramatically sanctioned by now, "ain't seen nothing" is still a double negative. making it incorrect English. Another issue to consider is whether the word "ain't' in its increasing acceptedness should be allowed to cover the territory of "haven't" as well as that of "isn't", "aren't" or "am not". The usual colloquial function of "ain't" is as a negative form of the verb "to be". But in a few phrases, like in this song's title line, it becomes a negative form of the verb "to have", since the standard way of stating the line is "You haven't seen anything yet", not "You aren't seen anything yet". So it is fair to question, however acceptable "ain't" becomes in lieu of "am not", "aren't" or "isn't", should it be further stretched to sometimes mean "haven't" or "hasn't"?
