I rock climb a few nights a week at a local gym and play on an indoor soccer team year round. I find that I really can't sit home doing nothing for more than one or two nights a week without going crazy. I often feel the need to be doing something at least mildly active after sitting at work all day.
I think everyone likes to laugh and enjoys humor, me included. I don't have a list of criteria or a checklist when searching for a partner, I'm just looking for someone I get along with, who's fun to be around, and has a touch of serious when it matters.
