A Brady Bunch question

[HairOfTheDog]

Jan Brady just sold her Malibu beach house for 3.9 Million. She bought it when she was 11 for $53,000. She was nuts, but smart with her money.
Jan also had the best hair. Marshas was thin and stringy.

That was a really smart investment. Her Malibu house was charming, old school beach cottage. Now, they're gonna tear it down and put up another artsy chic glass-front place. :(

Jan did have good hair. Cousin Oliver, not so much -- that bowl cut of his wasn't groovy at all.



So, why did cousin Oliver end up living in the Brady house and what nickname did the kids call him?
