What I have found out about the Shemp era of The Three Stooges is that all of the shorts produced in the 1940s were remade in the 1950's using lots of stock footage from previous shorts. It was a cost cutting measure used back in the day that mostly fooled all of us young viewers. This short, I'm A Monkey's Uncle, was recycled into another short, Stone Age Romeos, with what I estimate is around 50 percent of the same footage. (I actually watched them simultaneously). The latter just has a new beginning and ending.

So continuing this series, I now give you a simple traditional cache for the whole family to enjoy, and then a companion mystery cache, for which you can determine the coordinates using information from clips of both shorts.

First of all, from Wikipedia:

I'm a Monkey's Uncle is the 110th short film released by Columbia Pictures in 1948 starring American slapstick comedy team The Three Stooges (Moe Howard, Larry Fine and Shemp Howard). The comedians released 190 short films for the studio between 1934 and 1959.

The Plot:

The Stooges are cavemen living in the stone age. They must tend to their daily chores, consisting of mixing milk, hunting fish, and gathering eggs. Such is life in the prehistoric times. That afternoon, Moe has a date with his girlfriend, Aggie (Virginia Hunter). Shemp and Larry want to join, as Aggie has two sisters for the boys, Maggie (Nancy Saunders) and Baggie (Dee Green). When rival cavemen allege that the Stooges stole their women, a fight breaks out, with the trio catapulting rocks, mud and eggs at the cavemen. After fending them off, the victorious Stooges are free to woo their sweethearts.

Trivia:

I'm a Monkey's Uncle was remade as Stone Age Romeos.  The film title references the idiom "monkey's uncle".This is one of the few films in which Shemp imitates brother Curly Howard's barking routine. This was done in other films like Who Done It?, due to certain scripts being written for Curly before his untimely illness.
