Hmm. You propose an interesting question. At first I tried to think of someone who wouldn't feel the pain, or who would just be inconsequential to punch. I'm not really mad at anyone, but I do wanna see what it feels like. I thought about punching a random neanderthal, but then I was like, if I hurt them badly enough though, that could mess up a lot of future generations. I decided punching someone in the past isn't a good idea due to obvious time travel reasons. I guess I'll go with Kim Jong UnPersonally as long as its a quick in-and-out, and he never sees my face.
As for the hug, I can't just pick one person! Personally, I'm a hugger, and there is literally an infinite list of people (in the past and present) who could use a hug. I've been sitting here thinking for the past three minutes and I can't decide. So if I could hug anyone, I would hug everyone. Probably just in the present though.
My first impression was that you're an RP'er. I'm not very good at judging character, but I think the first times I really saw you, you were knee deep in RPs. You're pretty good at it too. Maybe a little too much ; I've noticed that on The Longest Thread, you've often tried to keep things linear.
