Mystery plants growing in my flower box

Hi everyone. I'm the one who posted recently about mystery plants growing in my flower box. Long story short: my parents gave me a container filled with soil to use as a flower box. Turns out one of them planted seeds in it before they gave it to me. They are swearing up and down that they are flowers, but I'm thinking they may be cucumbers.. Since the true leaf is in, I thought I'd post again in hopes of a concrete answer: Photobucket
