In the beginning of the Rugrat's All Growed Up special, after they are "all growed up", Angelica is talking to her friend Amanda about the Emica concert. Amanda talks about wearing retro clothes and that she was going to wear her mom's fur shirt. Angelica, on the other hand, didn't seem to know quite what retro was.

Later on in the episode, toward the end, you see Angelica and her friend in line for the concert. Notice-Angelica is the one wearing fur, and Amanda is just wearing something purple. Kind of a mix-up, wouldn't you say?
