Betty Boop appears dressed very scantily in this risqué short. Starting the next year, 1934, the Hays Office began cracking down on cartoon shorts, resulting in Betty's transformation into a more subdued, modest character.
After Betty fashions a bikini from palm fronds, she sings the first few lines of Irving Berlin's "All By Myself," written in 1921. This song has been featured in movies and TV shows such as Blue Skies (1946) and Battle of the Century (2011).
A reference is made to Betty's earlier cartoon Minnie the Moocher (1932), which was built around Cab Calloway's song.
Professor Bimbo's neon sign flashes between a head bump chart and and open palm. When it starts flashing faster it looks like someone thumbing their nose.
Professor Bimbo and Betty do the "walk this way" routine, which was popular in vaudeville before World War II. It even made it into a few mainstream movies, such as After the Thin Man (1936). The fad was famously reintroduced to popular culture by Mel Brooks in Young Frankenstein (1974), prompting Aerosmith to build a song around it.
