Can anybody help me with the details on this? I seem to remember there being a couple of crossover-themed nights on the NBC Thursday lineup with (I think) Friends, Mad About, Seinfeld and Fraiser, where all the shows were somehow connected.

Anyone else remember this?

Thursday Night Blackout
November 3rd, 1994
Mad About You - "Pandora's Box" - Paul wires an additional cable outlet to the bedroom causing a city wide blackout.

Friends - "The One With The Blackout" - Chandler gets stuck in an ATM vestibule with model Jill Goodacre when New York suffers a blackout

Seinfeld - "The Gymnast" - The producers chose to not participate in the programming stunt so no blackout affected Seinfeld's New York.

Madman of the People - "Birthday In The Bighouse" - Jack endures a miserable birthday during a blackout while Sasha & Meg are stuck on in an elevator with a good looking construction worker.

They also did something similar with their Saturday night, Miami based shows. The Golden Girls, Empty Nest & Nurses all experienced a hurricane.

I remember that. ABC also did that once with all their Wednesday night comedies; which at the time were "ROSEANNE", "GRACE UNDER FIRE", "ELLEN", and "COACH". They had all the characters go to Las Vegas, and run into each other.
