Although you might not master the Danish language good enough for a conversation, a large group of every-day-words you use in English actually has a Danish, or rather Old Norse origin; name of week days, maritime terms etc. You'll also find traces in English place names (e.g. in endings such as -by, -thorpe, -gate, and -toft), and some of these place names even have a Scandinavian personal names as prefix, such as Grimsby, meaning Grim's village.
