OT.com meme: luke sad pic/I care/WRONG PICTURE

I believe xhonzi started this one, just saying "I care" in response to someone posting "no one cares" or "who cares." I couldn't find the relevant picture so I just used the one of sad Luke being consoled by Leia after Ben died, which led to a brief "WRONG PICTURE" debate IIRC.

Ah, that would've been me :D

I think it was in a thread about protecting the users' kids from the prequels, something with xhonzi castrating an action figure of Yoda - although I don't remember how it was called right now.
Or it might've been a parallel thread from the same time period...

I also remember how everyone started quoting "WRONG PICTURE!!" immediately after, so yea, that's probably the origin :)
