Welcome to the world of
Mr. Rude, Mr. Crude, and Mr. Ugly!

Eleven-year-old Simon has been taught always to be polite, but in Aunt Mattie and Uncle Philbert's house, the rules are different. Even the animals -- including a loud-mouthed parrot and llmas named Mr. Rude, Mr. Crude, and Mr. Ugly -- say and do as they please. Aunt Mattie and Uncle Philbert tell Simon that good manners in their house mean thinking for yourself, saying what you think, interrupting -- and burping when you feel like it.

Simon is having a wonderful visit with his aunt and uncle, but what's going to happen when he tries out his new good manners at home?
