If you notice in this one episode, where Lil is at Tommy & Chuckie's house, and Phil is at his house, I think this episode is called Twins Pique. When Lil comes over, the camera goes back a little to show the whole play pen and most of the wall, about just after Lil starts crying, the wall is normally a pink/peach, but you see it green! When the camera goes back into the play pen, the wall is peach again. Hmmm ... didn't this episode have Larry and Steve paint the De Ville's house? Maybe they accidently painted the Pickles house while we weren't looking! LOL (Just kidding).
