Only Norwegian and English for me, though I understand a great deal of Swedish and some Danish (since these two are close to Norwegian). Funny thing is, Swedish is easy to understand when spoken while Danish is more difficult, but when reading , it's the other way around
I did once try to teach myself Welsh, for some obscure, long forgotten reason, but the grammar was hell, and I just couldn't figure it out.
Oh, and I speak fluently gibberish too :P
