Norway first applied to join the EU back in 1962, but was rejected due to French opposition. It's like they were trying to get into a exclusive club, but the bouncer (France) wouldn't let them in. Norway tried again in 1972 and 1994, but both times the answer was no.
Despite not being an EU member, Norway is still part of the European Economic Area (EEA), which means they follow many EU rules and regulations. It's like they're shadowing the EU, but without being a full member. This arrangement has its perks, as Norway gets to enjoy the benefits of the EU's single market without having to deal with all the bureaucratic red tape.
One of the main reasons Norway doesn't want to join the EU is because of the common fisheries policy. The EU wants to control Norway's fishing waters, which is a big no-no for the Norwegians. They're like, "Hey, these are our fish, and we want to keep them." It's a bit like a food fight, but with fish instead of pizza.
