Duckman (1994)

S04E18 Kidney, Popsicle, and Nuts

Duckman finds himself in desperate need of a kidney, but to secure one, he must locate a blood relative for a donation. Believing his father to be cryogenically frozen, he sets out to find him, only to learn that this man isn’t actually his dad. Utilizing the Microsoft Network (a not-so-subtle plug!), the twins and Cornfed track down Duckman's real father. When Duckman and Cornfed arrive at his location, they are shocked to discover that he is a paranoid schizophrenic who has established his own miniature nation.
