Cow and Chicken

Duck, Duck, Chicken (4x23)

:

Now Red Guy's Dr. Hiney, and says that Chicken is a deformed duck. With that, he takes Chicken to the hospital for a wattle-ex-tamy. After hours pass, Red Guy's surgery literally turns Chicken into a duck. Mom and Dad sue Red Guy, and lose. Now the Cow and Chicken show may be renamed "Cow and Duck".
