The weirdest object thrown at a football match

[RSL1]

Ha! I was at that Barca/Real Madrid Superclassico when Figo returned to the Nou Camp and the pig's head was tossed on the pitch. That game was the sole reason that I even traveled to Spain at that time. Everything I did was built around that match. And... the atmosphere was inspirational but the game play was actually really poor. Both teams were struggling with the rain-soaked field and it ended up a scoreless tie with very little possession. Just a pinball match.
