9x3 - Rugrats

When Taffy comes over to babysit the Rugrats, she is upset that the band will break up, all because they feel that she is affecting her performance in the band. When Taffy says, ""I'm not myself"", Angelica tries to cheer her up by dressing like Taffy. However, this created a new problem -- the Rugrats think that Angelica, wearing one of taffy's hair clips, has become Taffy; while Taffy, calling the bandmembers ""dumb babies"" over the phone, has become Angelica.
