The battle of Christmas songs with my friends.
Celebrating Christmas with my friends and colleagues in my place. We were 2 teams. Each must write lists of songs in a piece of paper and they have to sing those songs against the other team. The rule was, not to sing the same song that was sang by the other team and not to repeat the same song that was sang by their team. In other words, they cannot repeat the same song. We actually won on this one. :) :) :)
