I recently saw what looked like mini pumpkins on a thorny stock. Someone said it was probably rose hip. But I've never seen rose hips look like these. They thought it might be from a Rugosa rose. So I looked that up and it states that their rose hips look like mini crabapples. These were orange and definitely looked like mini jack-o-laterns, about 5-6 alternating on this thorny stem. Any idea what it was?
