Brits invented the language but Americans improved it.
Pronouncing "Z" as "Zee" instead of "Zed".
Removing the second "l" from words like "modelling", "travelling" and "panelling".
Replacing the suffix "ise" with "ize" in words like "organise" and "criticise".
Renaming the game of football to soccer, and inventing "American Football", despite using their hands (and not their feet) the majority of the time.
Pronouncing tomato as "tuh-may-doe" instead of the correct "toh-mar-toe".
Enlighten me. How are these improvements?
