France gifted Scotland a last-gasp try to lose 27-23 and hand Wales the Six Nations title on Saturday.
France had the match in hand, up 23-20 in injury time, but fullback Brice Dulin bizarrely decided not to kick the ball into touch with victory assured if he did.
The Scots exerted huge pressure over 22 phases, and left winger Duhan van der Merwe swept into the left corner in the 85th minute for his second try of the night and secured Scotland's first Paris triumph since 1999.
Eleven years after last winning the tournament, France needed a four-try bonus point win and a 21-point margin of victory in the tournament finale in an empty Stade de France.
The French did get three tries, but they also gifted points and possession and ended up second again, just like last year.
