Ok, so yes we all know that Blendin Blandin's wish was to erase Dipper and Mabel from exsistance, but would his wish actully erase them from existance, because there is a loophole if you think about it. 

if Blendin Blandin succeded in erasing Dipper and Mabel, he would have never met them so he would never have lost his job, which is what he wanted. but this would also mean that  he would have never challenged Dipper or Mabel to Globnar, therfore he would have never made the wish in the first place. 

If this were true, would the pines twins still be erased, or would the wish have no effect? this is up to your opinion.
