There Was A Pilot For A Series
It starred Ben Marley, Barbara Billingsley and Dick Sargent. All I can remember.
I'm wondering if Kari Michaelson, the eldest daughter from Gimme A Break, took over the Nancy McKeon role, but it was Ben Marley in Michael J. Fox's role.
Billingsley and Sargent were the principal and his wife, respectively.
Whoever the antagonist was here, he learned that hookers or women dressed as hookers were going to be on the school float, so he tells Sargent.
Other events took place and Marley had Billingsley in place on the float. Don't recall why whoever it was they were going to have on there couldn't do it.
So Sargent is braced to see what jezebel is on the school float and it comes around the corner with his wife sitting on it. Actually very funny.
