Your Mummy Is a Nose Picker

Based on comments of 10 year old boy.) This book is the last in a series of four so far (NP from Outer Space, Planet of the NPs, Invasion of the NPs, and Your Mummy is a NP). The main gag in the whole series is that the aliens look like they are picking their noses, but they are really operating internal nose computers. Earth has just become the main tourist attraction for tourists from the planet Pan. Pants, as they are called, love to go to the dentist, be stuck in traffic jams, and sneeze. But they are not able to sneeze, so they might not visit, and the Earth might be moved past Pluto as a result. To stop this, Stan from Pan and Devin from Earth go back in time to ancient Egypt to bring back Nile Delta Goldenrod, a weed that Pants are allergic to. They goof and change history. Now the world is one big Egypt!
