History
Bart once bought several funny stuffs to make his face more hilarious. However, they all fell off his face quickly. Homer gave him a super glue and Bart sticked the stuffs to his face again. However, when he tried to come them off, he couldn't. Marge then read a waring on the tube: "In case of accidental ingestion consult a mortician" and quickly took Bart to a doctor.
