Little Blabbermouse is at J.T. Gimlet department store. He is on a tour of the shop. During the tour he keeps harassing his tour guide (resembling W.C. Fields) Turns out the store is having a sale and everything must go, including J.T. Gimlet. The tour guide shows them hosiery with no runs, no hits and no errors; a painting of Whistler's mother, who whistles "She'll Be Comin' Round The Mountain"; and The Thinker, who keeps thinking about his 1940 tax form: "Confidentially, I think" (that's a radio B.O. joke). They take at a look at some robotic ashtrays, and a robotic poker table which shuffles, deals and even cheats. Shoes include red and green mules. Finally, the tour guide wraps up Blabbermouse with a sticker over his mouth that reads, "Do Not Open 'Til Xmas."
The blabbermouse starred in another short released earlier that same year "Little Blabbermouse", which was also directed by Friz Freleng.
No print with the original ending card was ever released on home video. However, a French Canal+ channel that aired this short prior to the release on The Golden Age of Looney Tunes LaserDisc in 1997 showed that original ending title card intact.
The edited soundtrack of dubs of both Turner prints (American and European) cut out the mouse's blabbering and mumbling with the 1941-55 ending rendition of "Merrily We Roll Along". The American and European Turner prints' original English audios, however, do not have this edit.
