FYI, the girl on the left being squirted was an unkown Goldwyn Girl....many years before she became famous.....Luciille Ball.
Stoogepedia notes are:
"The film marked one of the earliest credited appearances for a then blonde-haired Lucille Ball, who played a supporting role as one of the female recruiters and would herself become known for her own work in physical comedy in later years. Later in her career, when this short was brought up, Ball (apparently referring to the seltzer squirting scene) would remark, "The only thing I learned from The Three Stooges was how to duck. I still got wet!"
