These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ensemble Darkhorse: Nicely-Nicely Johnson is a very beloved character. It helps that he's funny and sings "Sit Down, You're Rocking the Boat."
Nicely-Nicely also appears in the 1942 Lucille Ball-Henry Fonda movie, "The Big Sleep." The movie was based on a Damon Runyon story, "Little Pinks." In this movie, Nicely-Nicely is played by Eugene Pallette instead of Stubby Kaye - and he doesn't sing. Lucy's character does, though.
