Benny even had a sound-based running gag of his own: his famous basement vault alarm, allegedly installed by Spike Jones, ringing off with a shattering cacophony of whistles, sirens, bells, and blasts, before ending invariably with the sound of a foghorn. The alarm rang off even when Benny opened his safe with the correct combination. The vault also featured a guard named Ed (voiced by Joseph Kearns) who had been on post down below before, apparently, the end of the Civil War, the end of the Revolutionary War, the founding of Los Angeles, on Jack's 38th birthday, and even the beginning of humanity. In one appearance, Ed asked Benny, "By the way, Mr. Benny ... what's it like on the outside?" Benny responded, "... winter is nearly here, and the leaves are falling." Ed responded, "Hey, that must be exciting," to which Benny replied (in a stunningly risqué joke for the period), "Oh, no—people are wearing clothes now." In one episode of the Benny radio show, Ed the Guard actually agreed when Jack invited him to take a break and come back to the surface world, only to discover that modern conveniences and transportation, which hadn't been around the last time he'd been to the surface, terrorized and confused him. (Poor Ed thought a crosstown bus was "a red and yellow dragon".) Finally, Ed decides to return to his post fathoms below and stay there. The basement vault gag was also used in the cartoon The Mouse that Jack Built and an episode of The Lucy Show.
