I wondered that myself, Divis. But then I figured it out. Watching replays will bear me out. As Zidane walked past Materazzi the Italian muttered "Help, I'm having a heart attack."

Zidane laughed, thinking it was a joke and said "Ho, ho. You Italians. Alaways joking."

As he gets 3 yards away Materazzi gasps "No, please, help me."

Zidane realises he is not joking and instantly administers an unusual but very effective CPR. Materazzi collapses with lack of blood to the brain and cannot speak for several minutes. In which time Zidane is sent off. By the time Materazzi realises what has happened it is all to late. Besides, he cannot now show dissent to the ref.

See? Easy...
