I am a firm believer in come as you are. If they ask that on an application, they want to know because they DON'T want boring employees. If you state your hobby in a way that isn't scary (mentioning restoring, shaving, antiques, etc.) then it cannot be bad for you. It will show your passion for something and more often than not, when people know that about me they get fascinated. I wouldn't leave it off the application completely but it's not me who is applying for the job.

On a related note– I was once interviewing at a temp. agency. Very formal thing. While I was getting interviewed I stopped the lady and asked her in a non-degrading way if she actually enjoyed her job. She was kind of taken aback but I went on to explain how a lot in that industry seemed so phony. She started laughing about it and talking honestly with me. Turns out it was pretty much the most interesting interview she'd ever given. After that she started calling me on a daily basis and I became her best/favorite temp ever. So take that however you'd like lol.
