Shazia Mirza has paid her dues beyond the way most comedians would apply that phrase. She always insists that she is not political, but the sheer heat of her subject matter has cost her dearly. 'I went to Mecca,' goes one joke. 'In front of the holy black stone, where you repent your sins, someone pinched my bum. I like to think it was the hand of God.'"
