OK folks - you are all showing your lack of AGE and EXPERIENCE. "If you think ... bla bla bla ... you gotta nother think coming" was something my MOM used when I was wrong or out of line when I was a kid and I was born 1945 - so cut the BS about the 80's - that is NOT when the world began. Can ANYONE tell us WHERE the phrase came from? I suspect an old time gangster movie line that would up in the coloquial slang sometime pre ww-2." HAS BEEN RESOLVED:

The Syracuse Standard, May 1898:
"Conroy lives in Troy and thinks he is a coming fighter. This gentleman has another think coming. It is probable that McCoy will next meet Joe Choynski."
ENJOY! And GROW UP.
