My hubby likes to repeat the old Shake & Bake commercial where the kid says, "And I helped."
I use: "I'll be back" and "Talk to the hand" from Terminator. "Just do it" from Nike. "Make my day" from one of the Dirty Harry movies. "I think we're going to need a bigger boat" from Jaws. When the kids want this, that & the other, I often say, "I'd like to teach the world to sing" from an old Coca Cola commercial.
We also use lines from songs quite often but it depends on the triggering event as to which song. "oo-oo that smell" is one we use quite often.
