Keyz,
This all depends on where you live and you have to give your driver's license number to prove that you're not lying about your location but the online mock juries do pay, if you can find cases in your area. You read/hear cases before they go to trial and then decide how much is an appropriate amount to ask for in damages or if they should have done something differently. It's awesome for someone who already likes Court TV type stuff. There's a bunch of different companies all over the US doing it, so you can sign up for all of them.
Here's one to look at:

You can sell plasma. The centers around here are usually packed since the economy isn't great.

I have a friend who is a great photographer but in this economy wasn't getting much work. She started cleaning houses with natural products. She made up fliers and business cards and bought some supplies. Within a year, she now cleans 15 hair salons. Businesses pay more than houses do. She listens to audiobooks and cleans a couple salons a night, when they are closed. Back in the 90's, I cleaned two bars. Gah, that was nursty. All that stale smoke and spilled beer but it paid awesome. Awesome enough to not have to do anything else all week.
I have another friend who is currently refinishing furniture for people. A lot of people have projects that they need to do but never get around to it. She has a truck, so she also buys wood furniture from yard sales and refinishes it and sells them at consignment shops and flea markets.
Another friend helps people set up booths at out local farmer's/art market. Between 2 booths, she makes 50 bucks a Saturday morning. She buys all her groceries with that money.
There was an article in last week's paper about a guy who started a grocery delivery service for shut-ins, when their families couldn't help.
Heather's family is paying people to do stuff for her mom, since she isn't able to do much. Painting a front porch, taking out ivy that's creeping in from the neighbor's yard, installing a ceiling fan, etc.
One of my mom's friends just takes down wallpaper for people. It's such a hated job that people don't want to do it.
