 Gene Siskel (qv) and Roger Ebert (qv) famously turned down  offers to guest star on TV shows and in movies because they felt it  would have been a conflict of interest. But this turned out to be  the exception and this is the only show in which they guest starred  together. The episode was called "Siskel and Ebert and Jay and  Alice" and the story is a parody of  _Sleepless in Seattle (1993)_ (qv) in which Jay and Alice attempt to  patch things up between the duo when one of their verbal feuds  causes them to split up.
