Marathon Goof

I was watching the marathon today when in the episode "A Matter of Record" right after the scene when Norton went to mail the record they cut to a commercial break.But when they came back the credits started rolling.They cut out the entire last scene which was when Ralph discovered that Norton sent the wrong record and the whole measles epidemic thing.What the hell is the matter with WPIX! Were they drinking on the job.To my knowledge this is the only episode this happened on.
