Duckman — S4E18 · Kidney, Popsicle, and Nuts

Duckman needs a new kidney. To get one requires a donation from a blood relative. He searches for his father, who he thought was cryogenically frozen. Instead he discovers that the man he thought was his father, wasn't. Using the power of the Microsoft Network (Blatant Plug!), the twins and Cornfed find where dad is currently living. Duckman and Cornfed travel there, only to find that his is a paranoid schizophrenic who's formed his own country.
