A Merry Mix-Up is a 1957 short subject directed by Jules White starring American slapstick comedy team The Three Stooges (Moe Howard, Larry Fine and Joe Besser).
It is the 177th entry in the series released by Columbia Pictures starring the comedians, who appeared in 190 shorts for the studio between 1934 and 1959.
Subsequently, the wives of the married trio appear, suspecting infidelity on their husbands' part upon witnessing the scene.
Amidst the ensuing chase, the engaged and single brothers enter the scene separately, further complicating the situation.
Luckily, Larry prevailed, and saved the studio from having to refilm thousands of dollars worth of exposures.
