English, Spanish, and Profanity 
Though, IMO, Spanish is the only language worth learning after English if you plan on staying in the US your whole life... My goals are Chinese (Mandarin), Farsi, Arabic, Urdu, aaand... we'll just go ahead and say Italian, it's pretty easy after the Spanish.
EDIT: Russian! Oh, I'm such an idiot.
