Keaton and Arbuckle's final collaboration is also their finest. With Fatty soon moving on to feature-lengths and Buster continuing as a solo act, the prolific duo came together one last time to entertain audiences (and themselves) in a typically short, simple silent comedy.

They're a pair of mechanics this time, serving double-duty in a combination garage / firehouse, and incapable of finishing one job without creating two or three new ones. The various props and occasions of a busy day in the auto repair business provide ample opportunity for clever laughs, which Arbuckle and Keaton casually pluck like fresh fruit from an overburdened apple tree. It's jam-packed with smart, funny, groundbreaking material; twenty-odd minutes of nonstop escalation. A posh suitor, interested in dating the boss's daughter, sees his neat white suit (and thoughtful flower bouquet) summarily ruined by the bumbling duo, who happen to be working with motor oil nearby. Wobbly vehicles are rented out with no chance of leaving the yard. An enormous turntable, once used to wash and inspect cars, becomes a high-speed human dry-cleaning station and, soon enough, a treadmill.

There's so much rich, creative energy jammed into this small package, it's hard to believe the masterminds behind it were about to split apart. In time, that divorce would work to Keaton's benefit. Arbuckle, sadly, wasn't quite so fortunate.
