Jackée (227)
"Jackée" is the 23rd episode from the fourth season of the sitcom 227. Originally broadcast on May 11, 1989 on NBC, the episode was a proposed spin-off for the Sandra Clark character portrayed by Jackée Harry. The series, despite airing as a special episode on a Thursday night between The Cosby Show and Cheers and having high ratings was not greenlit for production. For this episode, none of the regular characters appeared and only Helen Martin was featured.
At the time, Jackée and Marla Gibbs were in heavy disputes about many things over the series and Jackée admitted that when Sandra took off, so did her ego. Gibbs and Jackée later reconciled years later.
