Now that I have turned into my dad, I can just quote myself.
Yep.
One of my favorites from my Grandfather that I haven't quite aged into yet: "Boy, you're not worth a plug nickel!".
One that I have begun using: Saying that "We need to do this" but really just meaning the son doing the work while the dad sits back, drinks a beer and offers criticism. My dad still uses this one to this day. "We" recently climbed up on his patio roof and sealed it in the heat of an August day. "We" will soon be replacing the shocks, struts and mounts on his '05 Mustang. At least he lets me have a beer now, too.
