Chores for 5-year olds?

I need ideas for chores for 5-year-olds. Right now, Josh feeds the dog, helps unload the dishwasher and helps fold the laundry.

He has become fascinated with legos and would like to get some more sets so we told him he could earn the money by doing extra chores. Of course, he is thrilled but I can't think of enough appropriate things... Today he washed the insides and outsides of the downstairs windows. Other ideas, Moms?
