In the original airing of the episode on Oct 1, 1995: "Home Sweet Home-Dum-Diddly-Doodly", when Milhouse was telling Bart where he got a monkey from, he says "We bought this wicker basket from Pier One, and we found him passed out inside." In all syndicated airings of the show, the store name of 'Pier One' in that line has been replaced with "Trader Pete's". One can clearly see how the new words do not match with the animation. (However, in the UK, where Pier One isn't recognized, they air the original version.)
