A father and son went on a camping trip

An uneducated father with his educated son went on a camping trip.
They set-up their tent and fell asleep.
Some hours later, the father woke up his son.
Father : "Look up to the sky and tell me what you see?"
Son : "I see millions of stars."
Father : "And what does that tell you?"
Son : "Astronomically, it tells that there are millions of galaxies and planets."
Father slaps the son hard and says, "Idiot, someone has stolen our tent"

MORAL : Too much education can spoil or common sense.
