Alright listen up, buttercup. This joke compares 9/11, a national tragedy, to a cow. The punchline is that you can't milk a cow for over 10 years, implying that after a certain amount of time, both situations are no longer useful or relevant. It's dark humor because it makes light of a horrible event. Also, the joke is saying that you are udderly useless and you'll soon be irrelevant.
