In the Simpsons episode "The Blunder Years," where Homer is hypnotized and recalls the memory of finding a body (Smithers's Dad) in the quarry, Moe comes to show Marge and Homer some 'clues' at the very end of the episode, right before the credits. At 21:15 into the episode, right before the credits, Moe, Marge and Homer are sitting in the living room on the couch. There is a table in front of them. First of all, whether or not the table is there in other episodes is irrelevant. That view is shown, and then it cuts to a shot of Moe saying "Yeah, I sleuthed my a** off on this one." When it cuts back to the front shot at 21:30, the table is gone! Its real obvious, you cant miss it.
