Answer: What In The World Happened Here? XCV: (95)
There is a body of opinion that a cricketer actually hit the clock (that would be a Sixer). Probably an Urban Legend.
Given the Soccer Riot deaths in Egypt, my first thought was that "Cricket Riot" would return zero Google entries. Millions of results for "Soccer Riot", but the riot at the SGC at the 4th International Test was a surprise for me. And I traveled past the SGC most every day on the way to UNSW.
Of note is that one Umpire was Edmund Barton, who later became the first Prime Minister of Australia. He was a good bloke, and makes me think that "Umpire" is a better qualification for high political office than "Lawyer".
Also present - a rioter! was Banjo Patterson, who wrote "Waltzing Matilda".
The lesson here is to not pick a footballer to umpire cricket.
