A 'Welfare Check'
Checking the oven to see if there's anything edible left in there, because poor people use ovens like closets.
My mom checked the oven and found a bunch of old Tupperware and a burnt-up pan.
My neighbor checked the oven and found a used plate and some old spaghetti.
My cousin checked the oven and found a bunch of old pots and pans hiding in there.
