Here's a nice story I learned in the Norwegian ski museum:
In 1895, polar explorers Fridtjof Nansen and Hjalmar Johansen were having a bad time. Their expedition had faced some hardships and they were forced to stay on Franz Josef Land in a little hut they built out of mud and stones. In their hut, they slept for circa 20 hours a day, and spent the remaining four hours watching the northern lights or reminiscing about the comforts of home and the books they had read.
After several months of this, and nine months of sleeping in the same sleeping bag to stay warm, on New Year's Eve, Nansen finally gathered his courage and asked Johansen if they should start adressing each other with the informal you.
This is where the story ended in the museum, so unfortunately, I can't tell you whether Johansen answered yes or no.
