either nutt or butcher already nailed the "you are what you eat" one. I woulda came up with something like that too, but a little more stereotypical towards one race or profession.
Watermelon lips fried chicken legs, grape swishers as fingers etc...
Clean cut looking Cop eating in a diner, has a fork loaded with a cut piece of ham(thanksgiving style or someshit), his head is corked up looking at his reflection in the window, where there is a pig in the mirror image with the same uniform... Id make the pig all disgusting, probably draw something from inspiration of bloaty from invader zim. make the pig all fat with the uniform buttons popping off, hat tilted to the side practically falling off, lifting the same amount of ham up on the fork and looking up all hunched over the same way.
If you aint know bloaty, google bloaty's pizza hog, or watch some god damn invader zim cause that show is amazing
