Jennifer Aniston Laughed 'Hysterically' At 'Switch' Basting Scene

'It's one of those things where you go, 'That did not just happen,' ' actress teases to MTV News.

The underlying subject matter of Jason Bateman and Jennifer Aniston's romantic comedy "The Switch" — although a serious issue — is ripe with comedic possibilities in their upcoming film. In brief, Bateman's character, Wally, unwittingly ends up being the sperm donor to his best friend (Aniston), but doesn't find out until almost seven years later.

When MTV News caught up with the stars as they promoted the flick, opening Friday, we asked them to explain the technicalities of "basting" or "donating," as it happens in the context of the film.

"Well, you can't really give that away," Aniston told us, declining to reveal what happens in the switch/basting sequence. "Because that's one of those scenes in the movie, when I say I laughed out loud, I laughed out loud [when I read it in the script]. It's one of those things where you go, 'They did not just ... that did not just happen. Really?' And then, 'How is he going to get out of this one?' It's again, one of the things that made me laugh hysterically about this movie."

Bateman was far more forthcoming on the subject, specifically a broad description of the procedure.

"The basting process is one where a baster, which is an injecting item, needs to be placed firmly inside the female to introduce an element that may create a child," Bateman explained matter-of-factly. This made us wonder, does Bateman consider himself something of an expert on the topic since filming "The Switch."

"Unfortunately, no," the actor said. "I do not have any hands-on experience; it was just explained to me in theory."

While Bateman may not be a pro on the subject of insemination, he was downright philosophical when MTV News asked him to consider the sexier of two donations: blood or sperm? "Well, if I was in China, they wouldn't need any extra sperm. If we were in, let's say, Afghanistan, they might need some extra blood."
