Good part-time night jobs?

If I wanted to find a part-time job at night, to supplement my day job, what would you suggest? What are some that pay more than others? I guess I cant think of many beyond Waiter, bartender, freelance graphic designer? What are some to try that wouldnt be too hard to come by?
