Small jobs for kids

Help me out here. This was a small discussion in the comments section so I want to expand it a bit here. Can you think of small jobs you can have neighborhood kids to do? So far on my list are:
1. Rake leaves
2. Pick up trash
3. Water plants
4. Sweeping up the sidewalk or alley

When I was living in Logan Circle I also paid kids to get stuff from the Giant. That requires you giving them money and demanding a receipt. Also you have to know if they are allowed to go that far (or to cross certain streets) by their mom, or else you could get into trouble.
I have heard of other people paying kids to wash their car. Not any major detailing work, just soap and water and circular motions.
Part of a hesitancy with assigning some jobs depends on how well I know the kids’ parents and the kids. Another part is the risk factor of a job not done well. Will the kids step on the wrong plants? Will the task mess up what they are wearing and get his/her mother angry with me? Is the kid allowed to cross this street or go this far from the house?
So any suggestions you have to add? Pointers?
