Pretend you are on one of those reality contests where you have to lay in a vat of worms or snakes and to win a million pounds sterling all you have to do is lay there and plan on how you are going to spend your money. Substitute your sister to this reality game and just put up with her, no matter what.

2 Hire an assassin

3 Perhaps she would be a good candidate for me to bring the JIMMYT TRAVELING MOTORWAY PORTABLE THONG FITTING SERVICE. my Motto is, "I will bring the thong right to the crack, even at 140 KPH on the A25"
