As in the case of 'Royal Shiruko' (sweet-bean soup with a rice cake) (which changed from 'Revised Zenzai' (sweet-bean past with a rice cake) to 'Cultural Shiruko,' which was modified as 'Zenzai Co., Ltd.' which in turn changed to 'Maxim's de Zenzai,' all of which goes back to a routine transplanted from Edo rakugo), some routines were revised by many storytellers so that their contents changed over time.
「御膳しるこ」（「改良ぜんざい」→「文化しるこ」→「ぜんざい公社」→「マキシム・ド・ゼンザイ」。元は江戸落語からの移植）のように多くの演者によって手が加えられていくうちに演題が変わっていったものもある。
