I wouldn't list it.
I just helped someone get re-employed at my company who has been gone since 2004. She was an excellent employee, had kept in touch with people she worked with and let them know she was thinking about returning. They kept their eyes and ears open, and told them about a position I had. She ended up being over qualified for the position I had (even though she was willing to take a salary cut). A peer of mine had openings at the right level, she interviewed, and starts next week.
My recommendation is similar to comments you already have:
On your resume, only list professional jobs or other items that would relate to the position you are submitting a resume for. I was layed off in 2007 from the company I'm currently employed. I did 3 things for the 18 months I was "unemployed". Worked for my husband's company, taught children's music classes, and worked as a temp in my field. The only item I listed on my resume was the temp work in my field. The other 2 didn't apply.
Use the cover letter to very succinctly describe the gap in employment.
Work with a career resource center to help you find employment. There is one in my area that is very reasonable - $100. For that, you get a weekly meeting with an HR representative who can help you with your resume, give ideas on how to find employment, and go through a practice interview. It's www.careerresourcecenter.org.
Consider looking to refresh your skills, through a community college perhaps. These kinds of items could be added to a cover letter to show you are refreshed and ready to go.
I have been a manager for over 15 years and have hired many people.
Let me know if you want to chat more.
Best of luck!
