Vine with strange, prickly fruit

I found this vine in a park in Chanhassen, Minnesota. It has these strange, prickly-looking orbs growing out of it; but they're not hard spines. The fruit (?) is easy to touch, and the biggest one I saw was about the size of a quarter.

If it's not some crazy, invasive weed I'd like to try and slip it and plant it in my back yard.

Thanks!

 

It's wild cucumber, Echinocystis lobata, a widespread native species. I rather like them, both due to childhood memories of goofing around with the seed pods, and for the fragrant flowers!

 

I'd never seen one before! I hope it slips well.

Thanks for the info!

 

It looks like Wild Cucumber. We have them in Ontario. See link below.
