Jennifer Aniston has no clue how sperm banks work. Please advise

Jennifer Aniston had to discuss sperm banks with Jay Leno on the "Tonight Show" Thursday (July 29). But the topic was not out of the blue since "The Switch," her new romantic comedy that she also produced, is about a woman who uses one for have a child with a sperm donor.

Apparently, Jen has no idea how sperm banks work. FYI: No ATMs and no such thing as direct-deposit.

First, Jen gave Jay some of her brand new fragrance Lolavie, now sold at Harrod's, talked about moving to Greece when she was a kid and then about "Switch," and about what hard, hard work (and very, very lucrative, we might add) producing a movie is.

What you don't see in this clip is her dishing on being fired as a bike messenger in NY, loving three cheese thin-crust pizza with shiitake mushrooms and overcoming a fear of flying when she 'Judy Garlanded my way through the whole flight.'

In "The Switch," Aniston plays a young woman named Kassie who is ready to have a baby but is not in a relationship. So she decides to use a sperm donor. But her best friend, Wally (played by Jason Bateman), get drunk and swaps his sperm for the donor's baby juice. OK, euuuw.

Romantic comedy, confusion and capers ensue. If you liked "The Bounty Hunter," you'll love "The Switch."
