For me, English, a little Japanese, and chatspeak...Basic HTML as well (very, very basic)
I can remember how to count in Italian, I can say "I am a fish" and "I am a table" in French, and "I am a butterfly" "I am an onion" "I am a jam donut" "I am a cat" and a number of amusing things in German, but I don't think that counts.
My friend found out how to say "may the force be with you young Skywalker" in German, but he forgot.
