"Jerry on the Job" was a very popular Hearst strip in the 1910s and 1920s for no reason that anyone can figure out today. Given that everyone but William Randolph Hearst himself hated Krazy Kat and he was the only reason the strip survived -- he ordered every paper he owned to run it -- we can only shrug our shoulders and admit that some things so widely applauded today will seem equally pointless a century hence -- I'm hoping it's stuff like Jersey Shore. Anyway...This one looks like a a filming of one of the daily strips. The train station is overrun with mice. Jerry lures them to a lake by playing a saxophone. A train takes on the mice when watering itself and carries the mice back to the station, where they swarm. Structurally it's the basis of a joke, but the only amusing part is that instead of using a pipe to lure the mice, Jerry uses a saxophone.Oh well. It's very short.
