I disagree. Fish bones and tin cans is an excellent visual for someone living in a 1960s cartoon world slum, digging out of garbage cans. Ramen noodles are kind of a "modern age" thing.
I guess I'm not quite old enough to remember people digging stuff out of garbage cans.
On the other hand, back in 1995 I went through a tough period, using drugs, and me and a buddy
dug food out of a dumpster at a large grocery outlet. Food that was slightly out of date and
produce that was a bit on the old side. We had a feast. And then we smoked some more crack.
Seriously. We were a couple of cracked jerks.
