Watch How Anderson Cooper Was Forced To Live His Worst Nightmare On New Year’s Eve VIDEO

Comedian Kathy Griffin has a long-standing tradition of shocking television viewers with her inappropriate behavior, which includes dirty jokes, stripping, and dropping F-bombs, during CNN's live New Year's Eve broadcast.

This year, however, something equally weird was in store for viewers and Griffin’s New Years co-host Anderson Cooper.

Cooper apparently had had enough of his co-host’s nonsense and this year he decided to control her antics with a large sign listing some important rules: "No Swearing, No Stripping, No Touching, No Simulations."

Griffin, as unstoppable as ever, responded to his instructions by signing Miley Cyrus' name on the poster.
