The scene where Clair puts the flower on Theo's lapel took numerous takes, according to Phylicia Rashad.
In "The Cosby Show: A Look Back" documentary, you can see some of these bloopers.
Cliff: (to Theo) You still waiting for Denise to come out of that bathroom?
Theo: It's not fair, Dad.
Cliff: What do you mean fair, son? There's 2 men living the house with 4 women. We're lucky we have a gas station on the corner.
The presenter frequently calls Theo "Rudy," mixing up Cliff's only son with his youngest daughter. This could be an inside joke, as the part of the youngest Huxtable was intitially intended for a boy.
