After hearing the songs and laughing at the jokes about Zinedine Zidane's head-butt at the World Cup final, how about wearing a sweatshirt inspired by it too?

Italian entrepreneur Alessandro Ferrari has come up with a line of sweatshirts with two stick figures depicting the incident printed on the back.

The line's brand name is "Xqua", a play on the French word pourquoi (why in English) -- a question millions of fans asked themselves after the French playmaker rammed his head into the chest of Italian defender Marco Materazzi.

Ferrari said he was inspired by the incident to promote mutual understanding through a line of clothing.

"This message of peace is directed towards young people," he told Reuters. "We're nearly sold out. We're also working on accessories like bags and belts."
