Lisa is in the shower with soapy hair when two visitors arrive to see Oliver. She gets out of the shower to go get Oliver, and suddenly her hair is towel-dried rather than soapy as it should have been.
When Oliver takes a shower, he has to come outside to get the soap he dropped. After putting on his robe he steps out of the shower without fully closing it. As he steps back into the shower, a pair of boxer shorts is briefly visible under the robe. When Lisa takes a shower, she has to come out to talk to two visitors. As she emerges from the shower, she only uses a bunched up towel to cover her, revealing a light blue bikini behind the towel.
When the establishing shot of "Washington DC" is shown, it is actually the state capitol of California.
After Oliver tells Mr. Kimble about mailing his petition to Washington, an establishing shot is shown for Washington, DC with palm trees in it. Palm trees do not grow in Washington DC.
In the episode itself, the two fellas from the Conservation and Stabilization Committee are George Wilkins and Wally Jenkins. However, in the credits their last names are switched, and listed as "George Jenkins" and "Wally Wilkins".
