If you don’t know what Mark does, ask your parents. In his time, he has won awards (total is officially ‘f*ckloads’), forced a politician to resign, changed laws on tax and protest, become the Guinness Book of Records world-record holder for number of protests in 24 hours, taken the police to court three times and won, walked the length of the Israeli Wall in the West Bank, and generally mucked about trying to have fun and f*ck the right people off.
