Maurice Schwartz gets a job in a spice store. As low man on the totem pole, he does the deliveries, at which he is particularly inept. There's also a dog which attacks him and won't let go.
It's hard to think of the dignified star of the Yiddish theater, the man who first brought Sholom Aleichem's Tevye to the screen as a low-brow slapstick comedian, but the years change performances, and Schwartz is quite good in this one, particularly once the dog gets its teeth into his clothes. Indeed, it is the interaction between the two that makes this one stand out a bit from the typical entry in Schwartz' slapstick series.
Unfortunately, the dog is uncredited.
