S2·E19 Curious George, Plumber's Helper

George is tired of the same old tub toys. When he tries some new toys in the tub and drains it afterwards, all of the toys get washed down the drain! After trying to fill the tub with water again it backs up. The Man decides to call his plumber who always fascinates George with his work. The plumber fixes the clog and leaves, and the Man also leaves, to buy George some new bath toys. Afterwards, George is faced with another clog, this time in the dishwasher and decides to fix it himself, dismantling not only the plumbing in the apartment but also in the basement. After turning the plumbing back on, George winds up flooding portions of the apartment building.
