Hogan plans to use Schultz as an unwitting go-between in a plan to smuggle radio components to the Underground. The plan's success relies upon the possibility of Schultz being granted a week's furlough in Heidelberg. But several problems arise: Not only does Klink refuse to give Schultz a furlough, but the chubby sergeant has also had a falling-out with his wife Gretchen. The immense Barbara Morrison (best known for her comic-foil work on The Red Skelton Show) appears as the seldom-seen Mrs. Schultz, while frequent series guest star Parley Baer is cast as Dr. Pohlman. Written by Harvey Bullock and R.S. Allen, "Killer Klink" first aired on February 24, 1967. ~ Hal Erickson, Rovi
