Right Bed - Wrong Husband

Suddenly one day uncle drops in unexpectedly, and very much against his will Ted is drawn into the vortex of an intrigue initiated entirely by the uncle when he mistakes a pretty girl, married to Ted's best friend, as Ted's wife

Ted is basically honest and does not want to deceive his uncle, but every time uncle kisses the "wife" he ups the ante to say nothing of kindling the ire of Ted's friend; and Ted is not sap enough to turn that down

Complications come tumbling after when the maid calls and is mistaken for something else; when the real fiancee returns and is caught kissing Ted; but especially at night then the time comes to retire

Add the neighborhood drunk who habitually sacks in with Ted when he's locked out of his own house, and you have a climax of enormous merriment
