<<<<<<Hey, if Dallas can erase a whole season by having it all be just a dream, there's no reason Seinfeld can't erase that one ill-conceived episode. You forgot about Newhart...erased an entire what 7 season series...oh and thanks for mentioning Dallas, I can imagine that episode already...Pam finding Bobby alive in the shower... >>>>>
I think something similar happened more recently. On ...Married With Children, didn't an entire season turn out to be Al's dream/nightmare? Katie Sagal was expecting in real life, so her pregnancy was written into the show. Unfortunately, Katie miscarried. The producers (to their credit) were not about to make her continue the make-believe pregnancy and then have to handle a new-born on the show after such a personal tragedy. So they pulled a "Dallas," and presto---it never happened.
