Immortalized in the George and Ira Gershwin song "Let's Call the Whole Thing Off" is the nitpicking of pronunciation differences:
You like potato and I like potahto,
You like tomato and I like tomahto,
Potato, potahto, tomato, tomahto!
According to Wikipedia and other sources, the English do pronounce tomato as tə-MAH-toh rather than tə-MAY-toh. But this doesn't seem to be the case when it comes to potato.
(From the O.E.D.)
Is "potahto" actually an acceptable way to pronounce potato? Or is the song just wrong?
