Common Sense

An illiterate father with his educated son went on a camping trip. They set up their tent and fell asleep.

Some hours later, father wakes his son and ask:

“Look up to the sky and tell me what you see?”

Son: “I see millions of stars.”

Father: “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 ruin your common sense.
