On a flight, a man sat down next to Little Johnny and tried to make small talk.
“Hey there,” the man said. “I’ve read that chatting makes flights seem shorter. Want to talk?”
Johnny sighed, closing his book. “Sure,” he said. “What do you want to talk about?”
The man shrugged. “How about nuclear energy?”
Johnny nodded thoughtfully. “Alright, but before we dive into that, can I ask you something?”
“Of course,” said the man.
“Okay,” said Johnny. “A horse, a cow, and a deer all eat grass, right? But a deer leaves tiny pellets, a cow drops big flat pies, and a horse makes clumps. Any idea why that is?”
The man frowned. “No clue.”
Johnny leaned back. “Well then,” he said, if you don’t know s**t, maybe nuclear power’s a bit above your level.”
