The "Here's Lucy" crew played a prank on Gale Gordon. He expected the legs on the hospital bed to break, but instead the special effects crew rigged the bed to snap shut, forcing him to be folded in half. Although he masks his laughter, Gordon continued with the scene. In "Lucy Plays Florence Nightingale" Mr. Mooney (Gale Gordon) was also the victim of Lucy and a tricky hospital bed. Lucy also triggers a hospital bed to fold up with a patient (Jan Murray) inside it in "Lucy and the Soap Opera".
