Multi-Lingual?

I don't really speak a lot of languages (English, a little bit of Spanish and Japanese), but... do we got any people that speak more than two languages? Seriously, how can you remember all of that and understand all of that?

I can only speaks Filipino and English. I am really amaze with people who can speak more than 3 languages. I know someone who can speak Japanese, English, Korean and Filipino fluently, she was so amazing!
