He likes the strict regimentation of the institution (compared to the anarchy and choas of outside the institution) so much that he decides to have himself permanently commited. Cornfed comes to rescue Duckman from the institution, but is to late as he has already been given shock treatment. Luckily Cornfed has a book on brain surgery and gets Duckman back to 'normal'.
