Mattel recently announced the release of Limited-Edition Barbie dolls
for the Houston market:

Galleria Barbie:
This princess Barbie is only sold in Uptown Park. She comes with an
assortment
of Kate Spade handbags, a Lexus SUV, a longhaired foreign dog
named Honey, and a cookie-cutter house. Available with or without
tummy tuck and face lift. Note: Workaholic Ken sold only in
conjunction with "augmented" version.

Sugarland Barbie:
This modern-day homemaker Barbie is available with Ford Windstar
minivan and matching velour gym outfit. She gets lost easily and
has no full time occupation or secondary education.
Traffic-jamming cell phone sold separately.

Greenspoint Barbie:
This recently paroled Barbie comes with a 9 mm handgun, a Chevy
with dark tinted windows, and a meth lab kit. This model is only
available after dark and can only be paid for in cash, preferably
small, untraceable bills. Unless you are a cop, then we don't
know what the hell you are talking about.

The Woodlands Barbie:
This yuppie Barbie comes with your choice of BMW convertible or
Hummer H2. Included is her own Starbucks cup, credit card, and
country club membership. Also available for this set are Shallow
Ken and Private School Skipper. You won't be able to afford any
of them.

Friendswood Barbie:

Short, highly tanned and ready to
land a husband, we mean get an education. Comes with standard
issue UT shorts with "U of T" printed largely on the butt. Also
comes wearing latest "themed" sorority party T-shirt, hair in
pony tail and a gaggle of similar looking friends, each carrying
the latest in "knock off" Kate Spade bags. Honda Civic, undecided
major and drunken backward hat Frat Ken sold separately.

Dickinson / Texas City / Santa Fe Barbie: This pale model comes
dressed in her own Wrangler jeans two sizes too small, a NASCAR
shirt, and Tweety Bird tattoo on her shoulder. She has a six-pack
of Coors Light and a Hank Williams, Jr. CD set. She can spit over
5 feet and kick mullet-haired Ken's butt when she is drunk.
Purchase her pickup truck separately and get a confederate flag
bumper sticker absolutely free.

Clear Lake Barbie: This collagen
injected, rhino-plastic Barbie wears a leopard print spandex
outfit and drinks cosmopolitans while entertaining friends on her
boat. Percocet prescription available.

Pasadena Barbie:
This tobacco chewing, brassy-haired Barbie has a pair of her own
high-heeled sandals with one broken heel from the time she chased
Beer-Gut Ken out of Baytown Barbie's (discontinued) house. Her
ensemble includes low-rise acid-washed jeans, fake fingernails,
and a see-through halter-top. Also available with a mobile home.

West University Barbie: This doll is made of actual tofu. She has
long straight faded blue hair, archless feet, hairy armpits, no
makeup, and Birkenstocks with white socks. She prefers that you
call her "Willow." She does not want or need a Ken doll, but if
you purchase two West U Barbies, and the optional Subaru wagon,
you get a rainbow flag sticker for free.

Sharpstown Barbie:
This Barbie now comes with a stroller and infant doll. Optional
accessories include a GED and bus pass. Gangsta Ken and his '79
Caddy were available, but are now very difficult to find since
the addition of the infant.

Navigation Barbie:
This Spanish-speaking-only Barbie comes with a 1984 Toyota with
expired temporary plates and three baby Skippers in the back
seat, but no car seats. The optional Ken doll comes with a cowboy
hat, shovel and work gloves. Ken comes with his own 1979 Ford
pickup with a Telemundo bumper sticker, tinted windows, and Our
Lady of Guadalupe rear window stickers. Truck is painted primer
gray, but wheels and rims are not available. Comes with cement
blocks. Green cards are not available for Navigation Barbie or
Ken.

Montrose Barbie/Ken: This versatile doll can be easily
converted from Barbie to Ken by simply adding or subtracting the
multiple "snap-on" parts.
