This is heavily stereotypical, but you can judge the loyalty of an Italian-American with just two questions: Where does your mother live? What's your favor

This is heavily stereotypical, but you can judge the loyalty of an Italian-American with just two questions: Where does your mother live? What's your favorite [sports] team? If mom lives in the US, and the team plays baseball, NFL or NCAA football, or NBA or NCAA basketball, you could probably hand over the nuclear launch codes. If mom lives in Naples, and the team plays Euro-soccer, you'd better keep an eye on that guy. If mom lives in Windsor, Ontario, and the team is the Blue Jays, the test is inconclusive.
