While making the talk show rounds for her new movie, "The Big Wedding," the actress appeared on The Tonight Show and The Ellen Show to talk about tantric sex -- or, to be more exact, her character's interest in the ancient practice.

"When you have tantric sex you go for a long time and you have that thing called the orgasm," she explained, "for nine hours! For nine hours! That's ridiculous!"

Keaton breaks into hysterics on both shows explaining tantric sex and her role in the movie. Never married, the actress lets something slip about her thoughts on marriage that surprised Ellen DeGeneres. To find out what it was, watch the video above.
