For Larry Flynt, it's personal. He's loathed Hugh Hefner for years and is salivating over the prospect of kicking Hef out of the Playboy Mansion.
Well swapping out on slimeball for another no need to fumigate. :-)
Why would Flynt hate Hef?
I do know that Hef considers himself "highbrow", and always expressed disdain for Bob Guccioni, Al Whats his face from Screw magazine, and I'm sure Flynt.
Hef considers them sleazy.
