"sprechen sie Deutsche" is pretty much the only thing I remember from two years of German at GCSE. That and 'Ich habe zwolf jahre alt", which is less use now than it was which is not very much at all.
ich habe drei und zwanzig jahre alt, einen tiefgefroren bruder und ich spreche sehr klein, sehr scheiße 
(we had to look up a random adjective once, and i chose 'tiefgefroren' (=deep frozen). never forgotten that, but it's proper useless
)
