Resources for Learning Foreign Languages?

Mudhiker asks: "I'm tired of being a stupid American and knowing only two spoken languages, I wanna learn some more of 'em. The options at my local bookstore are overwhelming, so I ask Slashdot: What are some good (never mind the cost) books, tapes, packages...whatever...for learning foreign languages? Short of enrolling in college again or moving myself to another country, what are my options?" We did a similar Ask Slashdot focusing on linguistic software for Linux back near the beginning of the year. What other resources would you suggest for someone looking to broaden their verbal skills beyond English?
