As George is recovering in the hospital, The Man with the Yellow Hat see a newspaper story on it, and alerts the hospital that he would come get him. As George is waiting to be discharged, he finds a bottle of ether, opens it, and the fumes make him high, then dizzy, then knocked him out cold. When The Man and the nurse find him, they had to throw him in the shower to wake him up. (wikipedia)
