Smith is also known for writing the sequence where Pluto get stuck the to flypaper that was animated by Norm Ferguson in 1934 Playful Pluto.
Smith was one of the storymen who joined Walt Disney on the South American Goodwill Tour. His story ideas were rich with gags and good humor.
His career with Disney was short as he passed away in the mid to late 1940's.
