If you're asking about Migeru's last comment, then it's that old bit about British English and American English pronouncing potato and tomato differently.

Ella Fitzgerald and Louis Armstrong: Let's call the whole thing off

Things have come to a pretty pass
Our romance is growing flat,
For you like this and the other
While I go for this and that,

Goodness knows what the end will be
Oh I don't know where I'm at
It looks as if we two will never be one
Something must be done:

You say either and I say either,
You say neither and I say neither
Either, either Neither, neither
Let's call the whole thing off.

You like potato and I like potahto
You like tomato and I like tomahto
Potato, potahto, Tomato, tomahto.
Let's call the whole thing off

But oh, if we call the whole thing off
Then we must part
And oh, if we ever part, then that might break my heart

So if you like pyjamas and I like pyjahmas,
I'll wear pyjamas and give up pyajahmas
For we know we need each other so we
Better call the whole thing off
Let's call the whole thing off.

You say laughter and I say larfter
You say after and I say arfter
Laughter, larfter after arfter
Let's call the whole thing off,

You like vanilla and I like vanella
You saspiralla, and I saspirella
Vanilla vanella chocolate strawberry
Let's call the whole thing off

But oh if we call the whole thing of then we must part
And oh, if we ever part, then that might break my heart

So if you go for oysters and I go for ersters
I'll order oysters and cancel the ersters
For we know we need each other so we
Better call the calling off off,
Let's call the whole thing off.

I say father, and you say pater,
I saw mother and you say mater
Pater, mater Uncle, auntie let's call the whole thing off.

I like bananas and you like banahnahs
I say Havana and I get Havahnah
Bananas, banahnahs Havana, Havahnah
Go your way, I'll go mine

So if I go for scallops and you go for lobsters,
So all right no contest we'll order lobseter
For we know we need each other so we
Better call the calling off off,
Let's call the whole thing off.

A society committed to the notion that government is always bad will have bad government. And it doesn't have to be that way. — Paul Krugman
