John Herbert

Johnathan "John" Herbert, better known as Herbert the Pervert is a character from Family Guy. He made a cameo appearance in the episode The Simpsons Guy. Herbert is a creepy, lonely pedophile who lives on Spooner Street in a house all alone, with no one else, but an elderly, crippled dog named Jesse. Herbert kidnaps and molests underage boys, between the ages of 4 and 18 and is sneaky enough to stay off the radar of the police. The main boy that he stalks is Chris Griffin, who is oblivious enough to believe that Herbert is a good friend of his.
