Oi, Pain. You kill his sensei, kill his OTHER sensei, nuke his village, kill his other other sensei in front of him, impale his recently confessed love interest, and now your mocking his quest for Sasuke. Seriously man, why not just go up to him from the start and say "please beat the ever living crap out of me over and over again". I mean, really, your running out of ways to piss him off- short of digging up his mothers grave and roughing the corpse up a little....or having sex with Sakura and/or Sasuke in front of him, there's not a lot left to do before getting beaten to a pulp.
