Hmm. I never noticed you only stole it in this thread. I do think you're right though, this thread is about having the last post ever, and it does have some troll-bait characteristics.
I have to say, that it is kinda true that it's a redundancy thing stating your own name at the end of the post; however, if someone has an account that multiple people use, it may be an "authenticity" measure, where the poster is saying "I signed this, so it means I wrote this"; a sibling or parent is unlikely to notice such an idiosyncrasy.
I like the sigs because they are FUN!!!!

PS- I'm thinking of adding Possum and/or Weasel to my sig. Thoughts?
