Don't get me started.
The Americans make fun of us, but you should hear the mid-westerners. They pronounce it like it has an A in the middle, and HUGE emphasis on the ou. Kind of like abaOWt. People from California can't make up their mind whether it should be abat or abot, and will use both in the same sentence. Everybody else is reasonably normal.
Well, except people from Boston. They don't say anything correctly.
