Pardon my backfire is the 149th short subject starring the Three Stooges.
The Stooges are auto mechanics who need money in order to marry their sweethearts. While working in their auto garage, some escaped convicts pull in with a damaged fender. While the trio are working on the vehicle, they hear a news flash over the radio about some escaped convicts. They put the pieces together and realize that the baddies are right in their garage. After confronting the crooks, the crooks frame the Stooges for their crimes, crimes which cause the three Stooges to be put to death.
Pardon My Backfire was the second and last short made by Columbia with the Stooges in 3-D. It originally premiered on August 15, 1953 with the Columbia western The Stranger Wore a Gun (also in 3-D).
