Wild vine with little green 'pods', what is this?

I found a vine in the very back of my yard...which backs up to a big field. (I'm in Oklahoma). The vines have little green oval shaped 'pods', I don't know what to call them, that look like a tiny watermelon. About the size of a dime...or a little smaller. I've been researching on the net, but I don't even know what to be looking for. Does anyone know what this might me? Somethings that I know it is NOT are, poison ivy berries and wild cucumber.

Take a digital photograph, post it on a site such as Tinypic or Imageshack and copy and paste a link into your question. Then post your question both here and in the botany subsection of science and mathematics. That way you WILL get the right answer. Depends how badly you want to know.

Reply:these are called squirting cucumbers.....if you give the pod a gentle squeeze they will squirt their seeds up to 20'. They are not poisonous but I don't know if they are edible.
Reply:well, i dont live in Oklahoma (im in Oregon, actually) but i have seen something like that and i resurched them (this was about 2 months ago) and it was called a cucumber pepper! the wierdest name, but it is edible and they are (in my opinion) very intresting! i think it got its name from the lemon cucumber and green pepper...
Reply:Cardiospermum halicacabum, perhaps?

If it's that, it's a noxious weed in Oklahoma.
Reply:There's a possibility they might be peas.





However, you didn't give more of an in-depth detail.





Please be VERY cautious though however.
