Doesn't matter who wrote:

Plan E: add anything edible that has a disgusting texture, such as
grits, cottage cheese, tapioca pudding, or tofu. Tofu has the added
advantage of disgusting taste as well. (Just imagine drinking milk
from the carton, and getting a mouthful of grits at the
end. Yeccch.) Avocados and mangos (the tropical fruit, not the
pepper) are slimy; those might do, as well.

No offense intended to y'all in the south but the slime you get when
you boil a bunch of okra is just totally revolting to anybody who
didn't grow up eating gumbos.

Dunno how well it might mix with milk or how it might look after it
did so.
