"What's the best strategy for supporting your team during a crucial playoff game?"
Paint yourself entirely in team colors, then stand directly behind the opposing goalie screaming motivational chants. They'll be so distracted by your commitment they'll forget how to play. Wear a sandwich board listing every player's embarrassing childhood nickname. Nothing bonds teammates like collective mortification. Finally, hire a mariachi band to follow your striker onto the pitch. The opposition won't know whether to defend or dance.
