in "the abstinence" george is sitting on the couch messing with a rubik's cube while watching jeopardy... when he gets up to go in the kitchen the puzzle is nowhere near being solved... as he is standing behind the bags of groceries, he drops his hands while talking to jerry... as he is talking, he isn't working the cube but when he leaves, he comes out from behind the bags with the cube solved...
watching way too much seinfeld...
