Manners with Maggie is one of Perfect Peter's favourite TV shows, and one of Horrid Henry's least favourites. As the title suggests, the host of the show is Maggie. The show sees children from all over the country show the viewers how to eat nicely. In Horrid Henry Minds His Manners, Peter is invited to appear on Manners with Maggie while Henry is invited to appear on Gross-Out. However, due to a mix-up, they end up on the wrong shows. Peter gets splatted by Goo-Shooters while Henry wipes his nose with his sleeve. Maggie eventually goes crazy over Henry's bad manners and is dragged off the set screaming, resulting in her TV show being replaced by Mischief with Mildred.
