Mom always said don't play ball in another person's house... ahhhh never mind.

[jwyblejr]

They need to have someone make a joke about this on one of the sitcoms. It's too golden not to.

[MicromanZone]

Everyone is forgetting: The Mr. Rich-guy mayor of NYC had crabs. Makes you think!

[The Toyroom]

Carol Brady was always a ho....

[SlipperyLilSuckers]

Whoa harsh comments here and all directed to the one who received the unwanted gift as opposed to the irresponsible one (man - ho) who donated it.

It is ALWAYS the quiet one's you have to look out for.

oh sure she'd sleep with mr. crabs but not poor barry LOL LOL

That's the first thing I thought of

The Brady actors all have/had issues. Just because Florence Henderson played Mrs. Brady onscreen; it was pretty well known that she was nothing like that at all off screen.

Maureen McCormick (Marcia), wrote a book about drug addiction, weight problems, all kinds of messed up things. She did talk a bit about the cast and did confirm that she (Maureen and Barry Williams) did almost get it on and that Barry had a huge crush on Florence Henderson. I don't think Barry Williams or Florence Hendersen ever said anything happened between the two of them. One thing I have noticed about them...on the rare occassions they do get together, they really seem to genuinely like each other.

Back in the day I thought Shirley Jones was much hotter.

You know... there are some things best left UNSAID... That is just beyond nasty...
