If you don't care about the money and are just doing it to be socially acceptable, just start your own home business doing whatever you want. Sell stuff on eBay, mow lawns, or whatever you deem socially acceptable.

Given your background, one thing that comes to mind immediately is some type of business doing tutoring in math and science to high school and/or college students. There is always demand for this, hourly rates are decent, and you set your own hours.
