I remember a Bert in the tub skit done in the 90s. They used the same, Do The Rubber Duck, setting. It showed Bert in the tub singing, I Gotta Be Clean, with four anything Muppets behind him singing backup. Then soon, some animals like a dog, elephant, duck, chicken, penguin, fish, and alligator rise from the tub and join Bert and the AMs in the singing. Then it ended with everyone, excpet Bert ducking down and disappearing. And Bert goes, "Hey, who took the soap?!!" Bert certainly didn't feel embarrassed in that skit.
