I've done a bunch of neat things. I helped overthrow a dictator. I once talked an AI program into stopping a nuclear meltdown in Gamma World. I once rolled three twenties on a d20 in a row. I once filled a cannon full of chain on an abandoned pirate ship and by all means should have blown away the head bad guy just as he appeared in the story. That was actually pretty funny.
Nahhh. I don't like this question. Pride has never sat well with me.
