I saw the thread had reached 9 pages and though "Oh f*ck, I'll never catch up with all that!"
Then I read it... Damn you flub!
As I have no idea which surnames have been guessed (I stopped paying attention after the first dozen) I'll make some random educated guesses.
First, I don't think it's the same milkman who was called Oscar (don't know if anyone got this and connecting the two is just a joke....)
So I'm going to be a little judgemental (and probably racist) and assume that a milkman is more likely to be of an ethnic minority than American. It seems the kind of job that (over here anyway) many natives wouldn't want to do...
So first the top 20 Mexican/Latino surnames:
GARCIA, RODRIGUEZ, MARTINEZ, HERNANDEZ, LOPEZ, GONZALEZ, PEREZ, SANCHEZ, RAMIREZ, TORRES, FLORES, RIVERA, GOMEZ, DIAZ, REYES, MORALES, CRUZ, ORTIZ, GUTIERREZ, CHAVEZ
Someone's already done Polish... so I'm not sure what other minorities there are in the USA... or if this line of guessing is incorrect (which is entirely possible as the other name isn't particularly non-American)
Anyway, here I am. Crazy game so far.. hello everyone!
