That is quite a mad thing to include. Probably a joke added in by some programmer. Remember how some specific search-strings in Google would yield joke results? Same thing.

I tried switching the destination to Porsgrunn, my home town, just to see how it suggested getting from Denmark to Norway. But then it only suggested taking the Langesund - Hirtshals boat (step 71). I guess it figures you'd be too tired by then.
