I'm thinking Superman must have been Italian--perhaps his real name was Clarko Kento?
P.S. Speaking of super men, Happy Birthday to my Dad today!
Tanti Auguri is like saying Best Wishes, and Italians use it for all occasions. They actually say it more often than Buon Compleanno, which means Happy Birthday. In fact, the Italian Happy Birthday song goes like this:
Tanti Auguri a te,
Tanti Auguri a te
Tanti Auguri a Dad (this line doesn't flow as well, does it?)
Tanti Auguri a te!
Happy Birthday, Dad!
