"Dad", the young boy asked his father
"Yes, son?"
"Why is the sky blue?"
"I don't know, son"
"Why is the grass green?"
"I don't know, son"
"Why do birds fly?"
"I don't know, son"
So it went on, the son always asking questions and the father's response, "I don't know, son."

One day, the son said to his father, "Dad, I hope you don't mind my asking you all these questions all the time?"
"Not at all, son" replied the father. "How are you supposed to learn anything otherwise?"

In the second Parsha, Balak, G-d makes Bilaam's donkey speak to its' master. All of which goes to prove that if even a 'dumb animal' can display intelligence if G-d wills it to be so, then intelligence is surely a G-d-given gift.  Be intelligent, use your intelligence, but just remember this lesson and where the gift of intelligence comes from!
