It is the picture that has stomachs churning and people talking.
After Thanksgiving dinner a couple gave some leftover sweet potato casserole to their relatives. Four months later the casserole dish was returned - with the moldy casserole still inside.
The disgusting sight was photographed by husband and posted onto reddit under the tagline, "My deadbeat sister-in-law"
The casserole dish may have left in the back of the sister-in-laws car since November.
