Sinkin In The Bathtub is the very first short in the Looney Tunes series, released in 1930, starring Bosko, the Talk-Ink Kid and made by Hugh Harman And Rudolph Ising for Warner Bros. However, this was not the first appearance of Bosko — he first popped up in an unreleased 1929 pilot film.
The plot, if it can be called that, starts with Bosko taking a shower, approriately whistling to the tune of "Singing in the Bathtub". After some antics in the tub, along with the tub coming to life and ripping apart toilet paper, Bosko goes for a ride in his car to visit his sweetheart Honey. After a bit of serenading, they go off for a afternoon ride, and Hilarity Ensues.
Tropin' in the Bathtub:
- Alternate Company Equivalent: In addition to everything else, "Singin' in the Bathtub" was Warner Bros' response to MGM's "Singin' in the Rain" (written in 1929, years before the Gene Kelly movie).
- Animation Bump: The climatic scene where Bosko is being chased by his own car down the hill is animated with the background moving in perspective.
- Barbie Doll Anatomy: No genitals are seen.
- Early Installment Weirdness:
- None of the trademarks of Warner Brothers' animation are present here. It's a typical and almost unnotable 1930s cartoon. Also, Bosko speaks in a blackface dialect, which was swapped out for a falsetto voice after a few cartoons.
- The title card features various cartoon sound effects that are timed in with the theme tune, something which was dropped after this cartoon; though it appeared again towards the end of Harman-Ising's tenure with Warner Bros., oddly enough.
- Flat Character: Bosko, obviously.
- Looney Tunes in the '30s: The cartoon that launched their empire.
- Mickey Mousing: Being an early sound cartoon, this is to be expected. Everything is timed very precisely to the musical beat.
- Off-Model: The original poster◊ for the cartoon depicts Bosko and Honey has having ridiculously larger heads and smaller bodies, Bosko is wearing gloves and a different outfit than in the cartoon, and they inexplicably misspelled his name as Bosco.
- Public Domain Animation: The entire cartoon is in public domain.
- Public Domain Soundtrack: The copyright of the songs has long been expired.
- Pun-Based Title: On "Singin' in the Bathtub".
- The Quiet One: Despite being the first publicly released sound cartoon from Warner Bros., Bosko and Honey are given very little dialogue. The only lines of dialogue include the top quotes, Bosko yelling "Hey!" and "Mammy!", and the ending title where Bosko says "That's All, Folks!"
- Random Events Plot: Bosko takes a bath and drives his car to Honey's house, invites her for a date and drive. Hilarity Ensues soon after.
- Sentient Vehicle: Bosko's car, at least when it first appears.
- Shout-Out: When Bosko is running away from his car down the hill, he looks towards the screen and yells "MAMMY!", an obvious reference to the most famous scene of The Jazz Singer.
- That's All, Folks!: In the ending titles, Bosko says these words for the very first time in the franchise.
- Toilet Humor: Bosko's car coming out of outhouse with it's fanny flap down, revealing it's bare butt.
- Visual Pun: When Bosko and his own car are tiptoeing amongst the flowers, the song playing is "Tiptoe Through the Tulips".
- And of course, "I'm Forever Blowing Bubbles" plays when Honey dumps her bathwater into Bosko's saxophone, which turns it into a bubble making instrument.
