Ubbi dubbi

Ubbi dubbi is a language game spoken with the English language. Originating in America in the 17th century, it was popularized by the 1972–1978 PBS children's show "Zoom". When "Zoom" was revived in 1999 on PBS, Ubbi dubbi was again a feature of the show. Variations of Ubbi Dubbi include Obbish, Ob, Ib, Arpy Darpy, and Iz.
Rules.
Ubbi dubbi works by adding "-ub-" before each vowel sound in a syllable. (A linguist would say "Insert [ˈʌb] after each syllable onset".) The stress falls on the "ub" of the syllable that is stressed in the original word. So in "hello", which is stressed on the "he-" syllable, the stress falls on the "hub" in "hubellubo".
The method of adding "ub" before each vowel sound has been described as "iterative infixation".
Uses.
Ubbi Dubbi has also been popularized as the signature speech pattern of the cartoon character Mushmouth from the animated series "Fat Albert and the Cosby Kids", voiced by Bill Cosby. Cosby also used this speech variation in his famous "Dentist" monologue to illustrate the effects of a dose of Novocaine.
It was used in the episode "Mentalo Case" from the TV series "The King Of Queens", between character Spence Olchin (Patton Oswalt) and a salesman at a toy convention.
It was also used between Penny and Amy in season 10 episode 7 of "The Big Bang Theory" as a means of having a secret conversation, to counter Sheldon and Leonard's Klingon.
In the video game "Rayman Origins", the Bubble Dreamer speaks Ubbi Dubbi.
