Don't be stupid. It's tomAto! Unless you're a proper English gentleman. Which you ain''t. And I doubt anyone who ever reads this will be. It's tomAto. And after the creation of The New World allows us to put a fork in that two headed whore mother called.. "Bilingualism" our newunilingualism will dictate the pronunciation to be...tomAto.
In the new world, In the new world, anyone caught saying tomAHto, will find themselves on the business end of a flying cheetah donkey smash.
