Star Trek IV Plot

Tonight, L, our oldest daughter asks: "Can we watch Star Trek IV?"
Me: "Sure honey"
L: "That's Mrs. G's [teacher at school] favorite Star Trek. She says it has whales in it and they have to bring the whales back to the future." Pauses. "What does that [back to the future] mean?"
Me: "Well in the movie, they travel back in time to around the time daddy was a little boy [mid-1980s]..."
L: "WHHHOAAAA!!!!!!"
