The Zidane Head Butt

According to Zidan's Wiki page, appears Materazzi "Yer momma" jokes were minor compared to what he said later to set Zidane off.

And of course, no tragic ending is complete without a Zidane Head Butt flash game to make fun of the event.

Found at Mike Browne's blog.

[Edit]
opps, appears there is now a flood of animated parodies that anonymous gamers are producing that most be posted. These are even funnier if you know the video game referenced.
