Err... The US may not have an official language, but several states do, like the state I live in, Missouri.

When my daughter was a teen, we traveled from Indianapolis to Disneyworld in Florida.
On the way, we stopped at a Mickey D's some where off the beaten path in rural Georgia.
As we sat down to eat our meal, she said to me; "Dad; they sure talk funny down here!"
I replied, "No; WE are the one's who talk funny down HERE."
