- oldest sentence has been identified as Dutch: Maltho thi afrio lito ("I say to you, I free you, serf") used to free a serf.
- the most famous Old Dutch sentence is probably Hebban olla vogala nestas hagunnan, hinase hic enda tu, wat unbidan we nu ("All birds have started making nests, except me and you, what are we waiting for")
Too few tidbits to make a random tagline thingy out of and also is lacking as far as utf-8 characters are concerned. Oh well, I tried.
