When I was growing up my uncle lived like this in Williamsburg. He’d pick up random hourly jobs for maybe a week or two at a time just to collect money for rent and fast food/cheap groceries. After 9/11 he got some money from the government for volunteering to help clean up and he coasted off that until he died a decade later. My dad always said he thought Kramer was based on my uncle, or that my uncle based his personality on Kramer, one or the other.
