Dirty Work is a Pre-Code Laurel and Hardy short film classic comedy made in 1933.

Deranged scientist Professor Noodle is engrossed in developing a rejuvenation elixir for over two decades, purportedly capable of reversing the aging process.

Following an arduous exchange, Stan eventually joins Oliver atop the roof, albeit mishandling the apparatus, causing a disruption in the chimney's extension.

In a series of calamitous events, Stan's clumsiness results in Oliver's fall from the rooftop, damaging property and inciting chaos within the household.
