Sherlock Sleuth (1925)

House detective of the Hotel Omigosh, Cyril Fromage and his hotel switchboard operator sweetheart attempt to thwart a dastardly thief, "The Weasel," who is on the loose in the hotel, assisted by a sultry vamp. Plenty of hilarious gags along the way; including the operator taking a call from an irate lodger, so hot that it makes the switchboard steam. Taking advantage of the situation, she pulls out the offending plug and curls her bangs. The MGM lion even puts in a guest appearance.

Unfortunately the movie Sherlock Sleuth is not yet available on Disney Plus.
