Corey Lanskin is a boy that pretends to be British. He teaches Minecraft to adults for a fee in the Season Seventeen episode, "Informative Murder Porn".
Background
Corey is sought out by the adults who want him to teach them Minecraft, so they can remove the television block on their "murder porn". While he originally refuses to teach them, he is soon persuaded by Randy Marsh's offer of "a hundred ounces of silver". He takes them into his basement, which is loaded with multiple computer workstations, and uses a London cockney accent to instruct them, rather than his usual, child-like voice.
When the boys later come to his house, asking if he taught the adults how to play Minecraft, he tricks them by playing dumb. However, Eric Cartman catches on to the lie before they leave and they enter his house. They soon discover Corey's basement, filled with adults, and tell him that they were using Minecraft to block the adults from "watching spousal homicide shows". Corey tells them that to stop "murder porn", they have to talk to the cable company.
Personality
Cory acts like British actor Michael Cain in a crime film. He reverts back to an American child when manipulating children and adults when confronted about his scheme. In the end, Cory talks in his normal American accent after being exposed by the boys.
Appearance
Corey has blond hair in separated locks. He wears an orange t-shirt and gray pants.
