Tom Ripsin. Yeah, like the 'Green Fairy'. Which is a reference to Alcoholic Beverages that contained Absinthe. If you were fond of your booze in those days, you'd stare out through the bottom of the pint glass while drinking & whoever you caught sight of looked smaller than normal.
Sourpuss says to the duck as he's boxing the shark "stay with him. I'm right behind ya" like Jimmy Durante managing a boxer (Cagney's brother) in a movie called Palooka
Sourpuss. Ed Wynn "is" (note quotes-fine rhyme) Gandy. BTW No animation or voice credits, guess Paul Terry really wanted to keep the "illusion of life alive" aka Walt Disney (and Paramount, most MGM, and any non-Mel Blanc Warner Bros.like the RoadRunner or the Honeymousers, for instance.)
