"You can't educate pork." EXPLAIN!!! (please :] )?

Question

What does this saying actually mean?

5 stars for the best explanation =]

Answer 1

This saying means that you can't educate something with an inability to comprehend.

Answer 2

Well, it sounds like this old admonition:

"Never try to teach a pig to dance.  It will frustrate you, and it irritates the pig".

To be pig-headed means to be stubborn and possibly stupid, so it's saying that you can't educate someone who is not going to listen.

I cannot say that I've heard the phrase, though.
