9. Laura Niles as Laura
Though Laura only made one Californication appearance, it was certainly a memorable one. When Hank and longtime agent/best friend Charlie Runkle decided to have a threesome, Laura, a sexy California boxing instructor, was the lucky lady chosen. As could be expected, this situation ended poorly. Looking to surprise their respective men, Karen and Marcy, played by Natasha McElhone and the adorable Pamela Adlon, unexpectedly crashed the party.
