Talk of Jurassic Park makes me remember babysitting my nephew Jimmy, who was home sick but still wanted to watch the movie. He'd just gotten it on DVD and had seen it once. I put it on and Jimmy sat on the floor, cuddled in a blanket. He watched happily, talking to himself a bit about the various scenes and characters (he was just a little guy - maybe about seven or eight).
However, during the scene where bad guy Nedry flees through the park in the pouring rain, Jimmy turned to me and said "I'm going to go under my blanket now. You can tell me to come out when the guy washes his face." I'd seen the movie but was like huh?. There wasn't time to ask for clarification since Jimmy was already under his blanket. When Nedry's Jeep got stuck and the spitting dino showed up, a little voice rose from under the blanket, tremulously but determinedly singing "It's A Small World." All through the scene - while Nedry shrieked as the dinos tore him apart - Jimmy kept singing.
The very next scene opened with Dr. Grant splashing his face with water from a culvert. "The guy's washing his face," I told Jimmy, and he came out from under the blanket and continued watching the movie. The later, even more intense stuff didn't bother him at all.
To this day, I'm amazed that after one viewing, Jimmy had registered that Grant at the culvert was the "all clear" sign that the Nedry scene was over. And whenever I see that scene on TV, my brain provides its own soundtrack of a little boy singing it's a small world after all, it's a small world after all, it's a small, small world...
