I know what you mean. Every once in a while my neighbor's zucchini gets out of control and jumps my fence. The thing grows about 4' a day and in about 2 weeks there will be squash on the end. I give it back to him as I've never really cared for it, but obviously dire necessity would change that in a hurry. Maybe storing some zucchini seeds is the way to go?
