Topic #184: If you had a third arm, where would you put it on your body? Would you put it underneath one of your other arms? Or somewhere more interesting, say, the top of your head, so you could reach really high things? Or would you put it behind you, so it’d be a makeshift tail?
This topic annoyed me, so my answer was censored by my be-nice mind. I wouldn’t put it on my body, but yours. Leave the rest of my answer to your imagination.
