One poster in his review refered to Homer's incriminating photos being a reference to the Michael Jackson baby dangling incident, which may be a bit tough, considering how recently the event occured. However, being that the episode originally had Homer naming a star after the family (which went supernova), there is the possibility that the gag is a direct reference.
Given the fact that they only had to re-animate one shorter scene, how long would this have taken to re-integrate? Understandably, animation costs a pretty penny to produce and can only be produced within a certain time frame. Hence, there has been much discussion as to whether or not certain gags are re-written to accomodate current world events (ie: Michael Jackson baby dangling incident).
