On the right hand side of the "Cemex" banner you can see the greased pole. A ham is placed atop, and the fight cannot start until someone climbs up and claims the ham.
It takes hours to even get close to the ham, as people need to slowly knock off the grease until they can climb higher and higher. It's rather comical watching people climbing over each other, pulling each other down in a vain attempt to push themselves higher. Kind of like the corporate ladder!
The crowd would alternate between cheers as someone would get closer and closer, then boos when they inevitably slipped back down the pole.
Notice that yellow thing at the base of the pole? It's a guy wearing a banana suit. Mary enjoyed seeing him - she commented "Oooh ... is that how big the bananas get in Spain?"
