Note to Jennifer Aniston: put your cups of semen away when you’re done with them. If you don’t, Jason Bateman will get drunk, perform impromptu experiments, and your hopes of fertilization will go rushing down the drain. …Or will it?

In the trailer for The Switch, formally known as The Baster, Bateman plays a humdrum mope named Wally who switches Patrick Wilson‘s love juice out with his own. Here, come closer. **Hushed tone** See, the only thing is though, Aniston’s character was planning on using that love juice to conceive a child. So then guess what happens. She uses WALLY’S love juice instead. Then guess what happens! She has a kid! THEN GUESS WHAT HAPPENS!!! COMEDY!!!!!!!!!

The film is directed by Josh Gordon & Will Speck, the same guys who did Blades of Glory, and also stars Jeff Goldblum as the same best friend character he played to Hugh Grant in Nine Months. Why do people continually listen to Goldblum’s advice? The man has absolutely nothing of reason to offer.

Check out the trailer after the jump. The Switch inserts itself in theaters August 20th, 2010.
