hah. I always wondered about this too. I tried to imagine how it could be my own tv set up causing it somehow, because i couldnt see how they could let that slip through so consistently. It does always seem to happen when there is applause happening for about a second, but I know i've heard it for brief moments at other times as well. Always at the end or start of an episode, and only on comedy central. some kind of cross fade messup.
