Loudmouth George Earns His Allowance [PDF ebook] 

It’s summer vacation, and Loudmouth George is too busy having fun to do his chores. Now the house is a mess and his mom won’t let him go to the movies with Harriet. So George comes up with a brilliant plan. He convinces his brothers to do his chores for him in exchange for taking them to the movies-after all, they’ll surely be too tired to go after all the work! But each brother makes a mess out of each chore and now there is an even bigger mess to clean up. See who has the last laugh!
