Atletico Madrid weren't supposed to win the La Liga title. They were 100/1 underdogs before the season and even before the final the match of the season -- which Atletico only needed to draw to win the title -- most figured Barcelona would win it to take the league..
A Spanish brothel definitely thought that was the case, so much so that they were willing to offer free prostitutes if Atletico won the league.
And then Atletico won the league.
Now all of Spain gets to party, but the Atletico fans will probably pay anyone. Everyone is rich when they're drunk.
