Johnathan Babysits Rugrats : Season 5 Episode 8

Jonathan babysits the Rugrats at Charlotte's house while she's on assignment, but uses this opportunity to look for Charlotte's tape so he could ""dig up dirt"" on Charlotte for blackmailing purposes. However, he has to do this while humoring Angelica, as per Charlotte's orders. Meanwhile, the Rugrats dig up dirt (the one used to make mudpies, that is).
