Haunted Honeymoon
Larry Abbot (Wilder) and Vickie Pearle (Radner) are performers on radio's "Manhattan Mystery Theater" who decide to get married. Larry has been plagued with on-air panic attacks and speech impediments since proposing marriage. Vickie thinks it is just pre-wedding jitters, but his affliction could get them both fired.
Larry's uncle, Dr. Paul Abbot, decides that Larry needs to be cured. Paul decides to treat him with a form of shock therapy to "scare him to death" in much the same way someone might try to startle someone out of hiccups.
Larry chooses a castle-like mansion in which he grew up as the site for their wedding. Vickie gets to meet Larry's eccentric family: great-aunt Kate (DeLuise in drag), who plans to leave all her money to Larry; his uncle, Francis; and Larry's cousins, Charles, Nora, Susan, and the cross-dressing Francis Jr. Also present are the butler Pfister and wife Rachel, the maid; Larry's old girlfriend Sylvia, who is now dating Charles; and Susan's magician husband, Montego the Magnificent.
Paul begins his "treatment" of Larry and lets others in on the plan. Unfortunately for all, something more sinister and unexpected is lurking at the Abbot Estates mansion. The pre-wedding party becomes a real-life version of Larry and Vickie's radio murder mysteries, werewolves and all.
