at a meeting to "harrumph", to the point of singling out a man who did not say it. While it is generally expensive for the film makers to put distinct words in a specific background performer's mouth (as this would turn "extras" into actors during the sound mix, meaning they must be paid more), this problem can be avoided by recording gibberish that syncs with the on-screen mouth movements ("lip flap") of a specific background performer. It is thereby possible to make it sound as though an extra is saying something, when in fact they are not delivering any actual dialogue. This gibberish is known as "Snazzum", referring to the way in which the cartoon character Yosemite Sam would swear when angry ("Yassin Sassin Snazzum Frazzum!"). In Kung Pow! Enter the Fist a group of children in the background are heard exclaiming "Children! We're children" repeatedly. In season 5, episode 3 ("Let's Stay Together") of 30 Rock, Rob Reiner loudly and clearly repeats the phrase, "Rhubarb, Rhubarb, Peas and Carrots..." in a scene when a group of congressmen and women are muttering indistinct chatter. A similar reference is made by Jack Donaghy's assistant, Jonathan, in Season 4, Episode 14 ("Future Husband"). In season 2, episode 3 ("Potato") of Blackadder, Captain Redbeard Rum (played by Tom Baker) can be heard saying "rhubarb, rhubarb!" in a scene involving four of the characters talking over each other. In season 9, episode 8 ("Two Days Before the Day After Tomorrow") of South Park, congressmen can be clearly heard saying "peas and carrots", in sync with each other. In season 5, episode 20 ("Leo Unwrapped") of Will & Grace, characters Karen Walker and Jack McFarland clearly say "hubub hubub" and "peas and carrots" in a joke reference. In the Anthony Newley–Leslie Bricusse 1961 musical Stop the World – I Want to Get Off, the main character, Littlechap, is campaigning for elective office as a member of the Opportunist Party and makes speeches, all of which start with "Mumbo Jumbo". The initial lyrics, which are constantly revised, start with: "Mumbo Jumbo, rhubarb rhubarb / Tickety bubarb yak yak yak / Mumbo jum red white and bluebarb / Poor Brittania's on her back."
