If anybody here talks to Reykjavík (or is it Iceland) Radio going over the pond, you could try to impress them with this:
Good day: Goðan dag (the 'ð' is pronounced as the 'th' in ('this')
Good evening: Gott kvöld (the 'ö' pronounced as the 'ö' in Köln (the German town))
Good night: Goða nott
Good bye: Bless bless
