Borussia Dortmund, the winners of the last two Bundesliga titles, face the traditional might of Bayern Munich in the Bundesliga on Saturday. In anticipation of the game some Dortmund fans decided that the usual process of matchday insults wasn't enough, they needed to go one further. That one further was breaking in to the Allianz Arena late at night and plastering a giant Borussia Dortmund crest on the window of the VIP box, before turning the whole arena a lovely shade of Dortmund yellow.

Sadly, not meaning to ruin all the fun here but we have to admit- it's a viral ad for a spray chalk company. It is a little disappointing that it isn't real, and also a little disappointing that in this country we don't get ads this innovative or, as far as we know, spray chalk.
