If you want to experience the very best Norwegian musical humor, just react to the comedy duo Ylvis. The most famous skit is probably "What does the Fox say" - but I recommend starting with "Stonehenge" or "Massachusetts". Their song "Jan Egeland" is also a stroke of genius...
These guys are so talented. If u wanna watch more funny songs by them u can check out "hit for hit" too. Parodies of modern music by those two in this video. Kollektivet is good too. I recommend i "kygo's confession"
