Mom: Go and get a towel and clean it up, please.
Monkey: -blank expression-
Mom: (again) Go and get a towel and clean it up, please.
Monkey: -still just staring at the spill and Mom-
Mom: Okay, I will clean it up. (grabs a towel and mops up the mess)
Monkey: No! Me clean! Me!
Mom: Okay? There is a little bit more water in the cup. Go ahead and spill it so you can clean it up.
Monkey then spills the remaining water, gets the towel and cleans up the new mess. I think my son is going to be a janitor some day.
