We have a "chore jar" in our house. It contains slips of paper on which are written lots of little oddball chores that don't get done on regular basis: scrub around the handles of all the faucets on all the sinks; clean every light switch, etc. There are also some goofy ones: give Daddy a head massage and tell him how much you appreciate him; get out of chore free but consider this a warning, etc. When the kids forget to clean up after themselves and I have to tell them to do it, they have to pull a chore from the chore jar.
Emily has an amazing knack for pulling the slips that are goofy instead of pulling a slip with an actual chore. This week, she pulled the slip of paper which had "write a song about cleaning the house and perform it for your family" on it.
Here is her contribution to the musical cleaning industry:
