Father and Son went on a camping trip..
They setup a tent and fall asleep..
Some hours later, the father woke up the son..
Father: Son, look up to the skies, tell me what you see..
Son: I see millions of stars..
Father: Good, what does that tells you?
Son: Astronomically, it tells me that there are a lot of galaxies in the universe and planet..
Father slaps son very hard..
Father: You idiot!! Someone has stolen our tent.. Fool...
