Harry thinks that Bebe is interested in him as well, so he risks everything when Bebe ends up in jail. This lead to a lot of trouble for Harry. Throughout the whole ordeal Priscilla waits for Harry to face reality.
More recently, critic Maria Schneider reviewed Langdon's work and wrote, "Long Pants (1927), also directed by Capra, was a peculiar change of pace for Langdon, and possibly an attempt to poke fun at his baby-faced image by casting him as a would-be lady-killer; sporting little of the ingenuity of The Strong Man, it was a box-office failure that set off the comedian's quick decline into obscurity. An acquired taste, Harry Langdon's gentle absurdities and slow rhythms take some getting used to, but patient viewers will be rewarded.
Film critic Hal Erikson wrote of the film, "Few comedies of the 1920s were as bizarre and surreal as Harry Langdon's Long Pants...Written by future director Arthur Ripley, Long Pants is as kinky as any of Ripley's film noirs of the 1940s. Long Pants represents the second and final collaboration between star Harry Langdon and director Frank Capra, who was fired when Langdon wrong-headedly decided to become his own director, resulting in a series of career-destroying flops.
