Jennifer Aniston's streak of box office bombs continued this weekend with The Switch opening in a desperate 8th place, pulling in only $8.1 million in ticket sales.

Aniston was annihilated by The Expendables, that conglomerate of aging action stars including Sylvester Stallone (who also directed), Jet Li, Jason Statham and even Gov. Arnold Schwarzenneger in a cameo. In its second week, The Expendables outdrew Aniston more than 2-1, taking in $17.2 million.

Even vampires (Vampires Suck), lottery winners (Lottery Ticket) and fish (Piranha 3D) had more box office appeal than The Switch, which also stars Jason Bateman.

A Marley & Me sequel is sounding pretty good right now.

Jennifer Aniston Caught Up In Credit Card Scam

Lighthearted, surprisingly funny and buoyed by poignancy and punch lines, The Switch is a love story that starts with a partner-less pregnancy, and ends with warm fuzzies, after an unusual route.

Jennifer Aniston stars as Kassie, our pretty, successful and even-tempered heroine who opts for artificial insemination when, in her mid-30s, she’s single but still wants to be a mom. Things are going swimmingly until her bestie Wally (Jason Bateman) boozes it up at her pregnancy party, and  -- whoops! -- switches his sperm for the original batch. Suddenly, Kassie’s baby-to-be will be infused with the neuroses and social awkwardness that besets her hapless BFF, instead of alpha-male attitude from a strapping blonde named Roland (Patrick Wilson).
