Hey Pandas, Do You Say 'Tomayto' Or 'Tomahto'

Tomayto is the only right way to pronounce it,

If you call a tomato a tomahto you are a f*****g psychopath

I say "to-may-to". My 5yo, however, says "to-may-no". (It's just a quirk of him learning language, not a pun; tomatoes are his favorite veggie!)
