Not Your Father's Meaning

Example : 2001, Leslie Jaye Goff, Get Your IT Career in Gear!, ISBN 0072126833, page 3:  This is not your father's computer programmer. The days when the typical information technology professional sat in a cubicle all day hunched over a keyboard, a can of Jolt Cola and a half-eaten Twinkie within arm's reach, seem about as quaint now as a genuine whistle-stop political campaign in the mass media age.2005, Shoeless Wayne Santos, “Final Fantasy XII”, GameAxis Unwired, page 54:  Make no mistake about it, this ain't your dad's Final Fantasy. If you want an effiminate spikey haired main character with amnesia or serious social issues that must shoulder the burden of fighting a great and ancient evil, you're not going to find that here.2011, Peter S. Gaytan, For Service to Your Country: The Essential Guide to Getting the Veterans' Benefits You've Earned, ISBN 0806534834, page xv:  Just as this isn't your father's army — it's also not your father's VA. The bureaucracy is bigger, the forms have multiplied, the benefits have become more complicated.
