Muscle Up a Little Closer is the 176th short subject starring American slapstick comedy team The Three Stooges. The trio made a total of 190 shorts for Columbia Pictures between 1934 and 1959.
This was the first film to feature Moe and Larrys more gentlemanly haircuts, first suggested by Joe Besser. However, these had to be used sparingly, as most of the shorts with Besser were remakes of earlier films, and new footage had to be matched with old.The title of the film parodies the Otto HarbachKarl Hoschna 1908 song Cuddle up a Little Closer, Lovey Mine. ........
