Wanted: A Hobby

Walking across the parking lot to Which Wich today, my co-worker Christina, breaks the silence and asks, "Do you have a hobby?" Gotta tell you, I was a little taken aback and a little leery that I was going to be asked to join some Mary Kay cult or some such thing (Christina doesn't sell the stuff, and we actually had a good laugh about that one.) Rather, she was wondering because she feels like she is such a workaholic because she doesn't have a hobby, and perhaps, a hobby would give her reason to leave work. Upon further consideration, I don't really have a hobby either. I guess my house is kind of my hobby, but most of the time I just nap in said "hobby". I was kind of into gardening & such, and now all that is kind of grown in & established, and I just wait until Tuesday, my designated watering day, to um, water. I was a regular at the gym, and should get back to that, but I don't know if Using the Elliptical Machine qualifies as a real hobby. So here's my question - Do YOU guys have a hobby? Any hobby suggestions?
