Farina's mother is very ill and the mortgage is due. He tries to take over her laundry business, but the kids just wreck the clothes. Joe takes pity and devises a scheme to make money: the gang builds their own oil well.

Ten Years Old is a 1927 American short silent comedy film directed by Robert A. McGowan. It was the 58th Our Gang short subject released. It was remade as Birthday Blues in 1932. Nobody comes to Joe's birthday party so he goes to the rich kid's party with his own special cake.

The kids are playing baseball when a man dressed in Middle-Eastern clothing comes out and tells them to be quiet. They join Mary, Farina, and Scooter in the gang's hide-out while Mary is reading ghost stories. While on the other side of the wall, the Arab-looking man is cheating people out of their money by staging a fake séance using state-of-the-art special effects. The cave entrance for the gang's hide-out collapses, so they light candles and dig into the wall, entering into the house. The "suckers" find out they are being cheated and run to get the cops to book the guys. The guys find out that the kids are in the house, and one dresses up in a ghost costume and chases the kids throughout the house.

An abused chimpanzee escapes from a zoo. On the run, he meets Farina, running away from home and his battling parents. The two become friends and inspire the rest of the gang to put on a show to make money from neighborhood kids. But the chimp has his own idea and runs off creating havoc all over town until chased down by the local cops.

As a joke, several members of the gang convince Farina, who is "brave but superstitious", that he's caused the demise of a young acquaintance and must therefore lay the body (actually still very alive) to rest in the old burying ground, under the watchful eye of "the graveyard witch". The joke backfires spectacularly on the pranksters.

On Christmas Eve, the Gang copes with hardships, helps capture a gang of thieves, and learns that Santa Claus really exists for those who wish fervently enough.
