My favorite Milwakeean term is “bubbler” (drinking fountain). My brother and I would confuse gas station clerks all over the country.
Watermelon is "wootermelon" in some places.
If you toss in Canada, have fun with decal (deckel - generic term for warning labels) and process (long O, pro-cess).
Oh! Yeah! bubbler!!! Forgot about that one. Used to crack me up!
