When they dont get the hint that you arent interested,.what do you say?

Some people just dont seem to want to take no for an answer, and a good insult or sarcastic response is needed. to convince another person that you truly want them to move on...thing is, sometimes when we need it the most, that perfect remark eludes us. So give it up everybody...whats the best rejection line you ever heard? be creative, be heartless! lol.......so far my personal fave is cher telling jack nicholson in the movie "wiitches of eastwick." .."not only are you repulsive in every way, you arent even interesting enough to make me sick!" I stored that one in my mental archive for insults, to be uses at some future date! So how 'bout it everyone? hit me with your best shot!
