Lloyd: Pim, let it go!
Pim: Vice Principal is our next-door neighbor. I will never let it go!!!
Curtis: (To Phil and Keely, after not being invited to the dinner) Don't worry Curtis only take one hor'dourves . . . yes, party hat "a hint"!
Curtis: (to Phil, when he's told to go play Hide and Seek so he'll be gone and unable to go to the dinner party) Please, Curtis Cro-Magnon, not Neanderthal!
At the end of the show, the time donut has dumped everyone back to just before Mr. Hackett shows up. However, the next time we see Curtis, he is still dressed from his trip to find Lloyd and Barbara.
When Curtis comes out from underneath the sink (where he was hiding for a hide-n-seek game that he and Phil were playing 3 days ago), you can see that there is no plumbing beneath the sink.
