All's Well That Pretends Well - S8.E42

The Cirque du Dummi Bear show is coming to town, and Angelica really wants to go. There's only one problem -- she's coming down with a cold. The good news (to her, of course) is that Charlotte and Drew doesn't know about her cold yet, so she makes a scheme to hide the cold from them and make them believe that one of the other Rugrats have it.
