Looking into the cereal urination situation..........I think the problem here is that y'all have the expression wrong. Perhaps in some deep, dark, time in ages past, someone did say "pee in your cornflakes" but the expression just kinda' laid there, lacking something, much like soggy corn flakes themselves. Then it was updated and caught on in the newer, more alliterative form......."Piss in your Post Toasties."

You can readily see the improvement here and I have personally heard it that way since the 50's. I never heard the cornflake liine til sometime later and assumed the user was just uneducated in the nuances of the language and the insult.

So now you are all free to Piss in your Post Toasties, just keep it out of mine...................
