We really don't mean to imply that perhaps some in Germany are a little too excited about soccer right now — though perhaps not after yesterday — but some fans are actually falling for the oldest trick in the book.

World Cup pranksters in Berlin injured at least two soccer fans by inviting them to kick soccer balls that they had secretly filled with concrete, authorities said Tuesday. At least six concrete filled soccer balls were found chained to lampposts, trees and handrails across the city next to the spray-painted message "Can you kick it?," Berlin police said.

Police, pointing out many victims' bruised feet, said they had no leads, though our eyes are veering in the general direction of either the French, or the Road Runner.
