Biggest. Banner. Ever.
If you're at all familiar with soccer, you've probably noticed that fans in the stadiums are somewhat fond of unfurling giant banners. That is, they were fond of unfurling giant banners... until they saw this clip of the monster banner unleased by supporters of Uruguay's Penarol, at which point-- assuming they're human-- they would have been so emasculated that I imagine they couldn't have possibly brought themselves to bother trying again.
