Tennis fathers from hell

Damir Dokic – Currently the father of all hellish tennis parents, Dokic has scuffled with camera crews, smashed a reporter's phone and lain down in the middle of a busy road to prove a point. He's now serving a 15-month sentence for threatening to blow up the Australian ambassador to Serbia with a grenade launcher in protest over his daughter Jelena Dokic's claim in an Australian magazine that he abused her as a child.
