I've told Quocass this already and he's probably going to be the only guy that is going to read this.
Whilst on the train heading to padstow station, these junior east hills boys high kids sat next to me since chris leung and chuck weren't there for some reason. So anyways, they were exhanging 'yo mama' jokes. And their best jokes were literally:
Yo mama so old she appears in my history textbook
Yo mama is so dumb she went to Dr Phil for treatment for her best cancer.
...and we thought HAHS humour was shit.
