The Nerve is the 4th episode from season 4 of The Grim Adventures of Billy & Mandy.


Billy is again being bullied by Sperg and Mandy steps in to save him. Billy asks Mandy why she is so brave. Many reveals that`s because of a nerve. Now Billy wanted that Nerve and insisted Grim to make him small enough so he can get in Mandy's ear to steal that Nerve. Billy tricks the nerve and take it with him. As the nerve is gone Mandy becomes a coward even scared from butterflies. She also insists Grim to make her small enough so she can pay Billy back by taking the Nerve. Grim makes her small, she finds Billy's brain which was coughing and was weak and as small as an ant. He tells Mandy the Nerve is. When Mandy goes there The Nerve insults her which makes her angry and rude again. She took out The Nerve from Billy's head and commanded The Nerve to go away.
