A Napoleon Complex?

We were originally going to take Kevin's parents on an insane road trip all the way up to Tromsø, but because our usual catsitters were both on vacation this week, we ended up having to take a much shorter trip. We drove up to Røros, over to Trondheim, down to Ålesund, briefly visited the Jostedalen glaciers, on to Bergen and we finally spent 2 days in Oslo. Even though we didn't get to see everything that we had hoped to see, we saw a surprising number of the "world's biggest and best" sites. Since their arrival, Kevin's parents have visited the world's biggest cavern for public use, taken photos at Scandinavia's smallest stave church still in use, driven past Europe's deepest inland sea, driven through the world's longest tunnel, seen Norway's most visited stave church and admired the world's oldest steamboat still in use. Unfortunately, we didn't venture quite far enough north to experience the world's strongest ocean currents! (I'm sure they saw more superlative sites, but I can't remember all of them at this late hour.)
This fierce pride is also apparent with Norwegian food...there is a dessert called "Verdens Beste Kakke", or "World's Best Cake". I consider myself a bit of a cake connoisseur, and I can say rather definitively that Verdens Beste Kakke is nowhere near as delicious as a gooey chocolate cake, in fact, I don't know if it would even make the Top 10 List of Best Cakes Worldwide! At a gas station stop in Dale, I bought a couple of baskets of strawberries from a vendor who assured me that they were the world's best strawberries. It was all I could do to restrain myself from cracking up--I think the only reason I politely nodded and smiled instead of giggling maniacally was because earlier he had complimented me on my excellent Norwegian speaking skills!
Anyway, what is this national obsession with everything being the biggest, longest, first, oldest, best? Norway is a relatively small country--does it suffer from a nationwide case of Napoleon's complex? Or is it just trying to draw attention away from its rather dubious distinction of being the world's most expensive country? (Speaking of expense, the photo is of a toll bridge we crossed somewhere between Trondheim and Ålesund. It cost us close to $30 to cross it--not only were we charged for our car, we were also charged for all 4 people inside of the car. Even pedestrians are charged to walk across it! I guess in addition to all the biggest and best sites they saw, Kevin's parents also got to ride across the world's most expensive bridge...if there is actually a pricier toll bridge out there, I probably don't want to know about it!)
